1999/2000 Winter:
1. [ December+January+February ] - Averaged over England & Wales, the
SUNSHINE hours for December=65 (134%), January=63 (124%) and February=97 (133%)
(averages relate to the 1961-90 period); For the winter season as a whole, this
means that this was the SUNNIEST winter (as defined) in the entire record
(which started in 1907). Many places, especially in eastern & central
Scotland, eastern & southern England and the Midlands recorded record
sunshine. For London (Heathrow), there has been a total of some 257hr; There
have been very few occasions in London with sunshine totals above 200hr.
According to Philip Eden (Telegraph), since the record began in 1876, the
events were: 1948/49=206hr; 1951/52=208hr; 1979/80=207hr; 1983/84=229hr;
1987/88=209hr; 1997/98=226hr and of course, 1999/2000=257hr. [ NB: record not
made up from the same station.]
2000 (April & May):
1. A notably WET pair of months. Using the EWP series, April 2000 plus May 2000
was the second wettest such combination (wettest=1782 !). This was not
surprising, as the April (2000) was the WETTEST April in the EWP series
(beating the 1782 figure). The words 'FLOODING' cropped up quite a bit in these
two months - for April, the rainfall was fairly uniformly spread about England,
Wales & NE Scotland, with 200 to 300% of average. In May though, the
excessive rainfall was much more regionalized - over 200% southeast of a line
Whitby/Bournemouth, with some spots in SE lowland England circa 300%. [ see
also 1983 & 1782 ]. Some spectacular THUNDERSTORMS in May - including one
at Bracknell, the home (until late summer 2003) of the UK Meteorological
Office!
2000 (Autumn):
1. For the England & Wales series, it was the WETTEST autumn since that
series began in 1766. The final total was 503 mm, which is 196 % of the 1961-90
average. SIGNIFICANT FLOODING occurred over England & Wales, and also more
locally over Northern Ireland, south and east Scotland. For Northern Ireland,
it was the WETTEST autumn since at least 1900 and in the Belfast area, perhaps
the wettest autumn since 1814.
>> The Environment Agency (who look after England & Wales
only) suggests that up to the end of November, the flooding was the
worst since 1947 (though note carefully that the meteorology &
hydrology of the '47 floods was different. However, in York, it is thought that
the FLOODS were unprecedented in the past 400 years. (Also worth noting that
historically it was probably wetter about a thousand years ago!)
> September: most areas well above average .. 175 to 200% much of England
and SE Wales, also areas of E. Scotland. Locally Yorkshire, Lincolnshire,
>200%.
> October: the WETTEST October (England & Wales) since 1903 with 188mm,
and the second wettest October in that series. It was also exceptionally
wet in eastern counties of N. Ireland & across some parts of SW Scotland.
> November: 182 mm in the EWP series, the WETTEST November since 1940 &
the fifth wettest November in the EWP record.
2. Manchester (Ringway) airport recorded NO FROST in the three months
September, October and November this year (2000). This was unprecedented in
their record which began in 1942.
2000 (Annual):
1. The WETTEST (calendar) year in the EWP record since 1872, and the
third wettest in that series. Total=1233 mm/135% of 1961-1990 average.
It included the WETTEST September to December period on record, the wettest
Autumn (q.v.), the wettest April (q.v.), the second wettest October, the 6th
wettest November and the second wettest April & May pairing (q.v.). [ see
also 1768, 1852, 1872 & 1960 ]
> Many central southern & southeastern counties (south of London) of
England exceeded 1000mm of RAIN, with upwards of 1300mm in parts of Sussex. The
DRIEST area this year was around the Wash/eastern Fens & east coastal East
Anglia where some places recorded just under 700mm of rain.
2001
2000 (Oct)/2001 (Feb):(5 months):
1. Above average SUNSHINE in the Northern Isles. For Lerwick (Shetland) &
Kirkwall (Orkney), the accumulated values for these months are easily the
highest in the respective records for these autumn/winter months.
2000/2001 (6 & 12 month periods):
1. According to Philip Eden (RMetSoc/Weather Log): " the six-month
period September 2000 to February 2001 was unprecedentedly WET over England
& Wales. At Herstmonceux (East Sussex) 1154mm fell in this period compared
with a mean of 426mm" This represents some 270% of the average, and
indicates how the highly notable wet weather has been concentrated across
southern UK.
2. The 12 months from April 2000 to March 2001 in the EWP series is the WETTEST
such 12 month period in that record (starts 1766) with a total=1355 mm; this is
not far short of 1.5 times the 1961-1990 average. For parts of SE England, the
anomaly is probably well in excess of 200% - and current thinking is that this
may be an event that has not occurred for many centuries!
1999-2001 (24 months to end March):
1. The 24 month period ending March 2001 was the WETTEST in the EWP series.
2001 (February):
1. PROLONGED/HEAVY SNOWFALL affected eastern Scotland & NE England 3rd to
5th. Shetland, Fife, Tayside & Aberdeenshire amongst worst affected. A
train (15 pax & crew) was trapped by SNOWDRIFTS in the north of Scotland
(en-route to Wick), electricity was cut-off to roughly 11000 households after
SNOW/HIGH WINDS brought down power lines, many roads closed and an Inverness to
Edinburgh train was de-railed (nr. Killiekrankie) after it hit a tree brought
down by GALES. Many schools closed.
> A depression moved slowly south-eastwards across the British Isles during
the 26th & 27th & SNOW fell heavily across Scotland & N. Ireland,
DRIFTING in the strong wind. Once again, reports indicated that transport was
severely disrupted. Large accumulations south of the border were confined to
Northumberland, Durham & North Wales.
2001 (October):
1. Record WARMTH by the CET record, also for eastern Scotland. The
(provisional) CET value=13.3degC (+2.7 on 1961-90 climatology), easily beating
the previous October CET record of 13.0 set in 1969. The difference was most
notable in the mean overnight MINIMUM TEMPERATURE, and there were no AIR FROSTS
recorded. For individual stations (using the 1961-90 average), Dyce (Aberdeen),
Eskdalemuir (Dumfries & Galloway), Cambridge and Hurn (Bournemouth) all had
mean MINIMA 4degC or more above, with the anomaly at Cambridge +4.6degC. The
night average at Heathrow (11.3degC) was some +3.3 above average, and was the
highest (for October) in that station's record which began in 1946. In many
parts of the UK, the month was warmer than September 2001. (Also WET by the EWP
series: ~ 160%)
2001 (November & December):
1. In November, 2001, anticyclones dominated the weather, with PRESSURE
anomaly +10 mbar or greater over Wales and the West Country. Specifically, a
large anticyclone settled over the British Isles from the 14th to the 20th
November, PRESSURE peaking at 1044 mbar at midday on the 16th - not too far
from the known 'highest' for November. December also experienced
anomalously high PRESSURE. A 'mean' high was centred over the Channel Islands
(central value ~ 1025mbar), with an anomaly centre south of Iceland in excess
of +16, and anomalies across mainland UK ranging from +9 in southern England to
+14 in the far NW of Scotland. Philip Eden (Weather Log/R.Met.Soc) says
that with the mslp exceeding 1040 mbar somewhere in the UK daily between 8th
& 19th, this may be unique in the instrumental record.
2001 (December):
1. SUNNIEST December on record over large parts of UK (& specifically by
the composite England & Wales record which began in 1909**). Several sites
>=200% of LTA., e.g. Heathrow (London) 93hr/203% & Aldergrove (Belfast)
78hr/200%. ** [ The England & Wales sunshine figure=2.6hr/day (183%).](see
also 1999/2000 winter)
2001 (Annual):
1. Another WARM year. The GLOBAL average surface TEMPERATURE roughly
0.4degC above the 1961-90 average, in the 'top-5' WARMEST years in record which
started in 1860. (Warmest 1998: q.v.) Nine of the 10 warmest years had occurred
since 1990. (reflected in the CET record, with a provisional anomaly of
+0.5degC of the 1961-90 LTA .. probably less for the 1971-2000 base-line though
~ +0.2degC, and a long way short of being in the 'top-ten' of warm years by the
CET.)
2002 (March/April):
1. Notable DRY spell in southern Britain.
2002 (September):
1. DRIEST September Aberdeen (Dyce) & Plymouth (Mountbatten) since 1959.
2002 (October & November):
1. A notably WET (& MILD) pair of months: by the EWP (CET) series, though
not 'record-breaking' as such. Some local all-time records set, e.g.
Aberdeen, St. Mawgan (nr. Newquay, Cornwall) and Aldergrove (nr. Belfast).
Eastern Scotland had it's second WETTEST (areal average) October on record.
Also, using areal-averages, the south & SW of England probably had one of
their WETTEST Novembers in at least 150 years, perhaps longer (some sources say
THE wettest - though I have my doubts about this). Northern Ireland also had a
notably wet November.
2002 (into early 2003) (October - December, into early January 2003):
1. The three months October to December 2002, using the EWP series, were the
third WETTEST in that record. With depressions taking a more than usual
southerly route across the British Isles, exceptional autumn and early-winter
rainfall was the result across southern areas. The concentration / frequency of
high-rainfall events was not quite of the order of 2000 (q.v.), but FLOODING
did result, with the Thames Valley particularly affected - the events
spilling-over into January 2003.
2002 (Annual):
1. Another WARM year. (CET=10.60degC/+1.1degC [ on 1961-90 means or +0.9degC on
1971-2000 means ] (fifth WARMEST .. behind 1949, 1990, 1999 & 2006). Mainly
due to January to April 2002 being extremely MILD, with MAXIMUM TEMPERATURES in
February the second HIGHEST on record; night-time TEMPERATURES also noteworthy
for being well above average in several months - implying increase in humidity
values over the year as a whole; the average annual MINIMUM CET placed it
second-warmest (after 2004) in that series. According to the Hadley Centre (at
the time), five of the six warmest years in the full CET record have occurred
since 1990, the one 'outlier' being 1949.
2. Global surface TEMPERATURE (Land & Sea) was apparently the second
highest in the appropriate series since 1860: +0.70degC anomaly - nine of the
10 warmest years in that series have occurred since 1990, including 2000 &
2001 - only 1998 was warmer than 2002. By Land-series only, it was the WARMEST
in the record. 3. Notably WET in some parts of the UK. By the EWP series, the
total=1118mm (121%), placed it at number 10 in the series 'top-10', but looking
at the past 100 years, the total was only exceeded four times (1903, 1927, 1960
& 2000). For Aldergrove (Belfast airport) specifically, the year saw a
total of 1095, the WETTEST year in that station's record (started 1927), the
previous highest being in 1966. No individual monthly records broken, but the 3
months October to December were the third WETTEST on record. In northern
England, rainfall in February beat the previous (areal-average) value by 2mm.
FLOODING was again a feature of the news, though not the widespread/intense
events of 2000.
1998-2002 (5 year period):
1. According to COL the period 1998 to 2002 inclusive was the WETTEST five-year
period in the EWP series (which starts in 1766); the total = 5419 mm.
The others are: 1875-1879 = 5205, 1876-1880 = 5197,
1997-2001 = 5145 & 1878-1882 = 5107mm.
2003 (January): HIGH (LOCAL RECORD) UK TEMPERATURES
1. On the 26th, a MAXIMUM TEMPERATURE of 18.3degC at Aboyne, Aberdeenshire.
This equalsthe previous record for January in the UK, set at Aber, North
Wales on the 10th January 1971 & 27th January 1958.
2. In England, 17.4degC was recorded on the 26th at East Malling (Kent) and is
apparently the highest January regional value for the SE of England:
previous highest 16.3degC at Gravesend-Broadness (Kent), on 6th January 1999 -
though there are considerable doubts about this station's readings /
exposure etc. (based on 'Weather'/RMetSoc & MetO press releases)
2003 (April): HIGH TEMPERATURES - NEAR RECORD APRIL UK/RECORD
SCOTTISH
1. Very high TEMPERATURES mid-month (with heath/moorland FIRES breaking out -
mainly started deliberately). On the 16th, Wolverhampton MAXIMUM TEMPERATURE
= 27.3degC, the HIGHEST April temperature in the UK since 16th
April, 1949 (Met Office). Individual station records (varying record-length)
broken in many places, and on the 17th, the afternoon MAXIMUM of 26.9degC at
Lochcarron (Western Highlands) set a new April temperature record for Scotland,
beating the previous record of 26.7degC (?80degF converted?) at Dollar
(Clackmannanshire) in April 1870.
2003 (January - April): NOTABLY SUNNY - LOCAL RECORDS BROKEN IN
MARCH
1. For the period January to April (inclusive), the total SUNSHINE across the
UK was remarkable. Philip Eden (WeatherOnline) states: " The first four
months of 2003 have provided .. the SUNNIEST start to the year since
1893". The averages (from Met Office site) over England & Wales=149%
(Feb: 152%, Mar: 166%); Scotland=138% (Mar: 166%); N. Ireland=139% (Mar: 169%).
[ anomalies wrt 1961-90 averages ]. Inspecting the graphical output, it appears
that Northern England has benefited most with an overall anomaly for these four
months=153%.
> Feb: sunniest since 1988, with anomalies at least 140% and locally over
160%; Northern Home Counties, East Midlands, East Anglia and areas around the
Solway Firth particularly blessed.
> Mar: Regarded as SUNNIEST March across England & Wales 'on-record'
(probably since early 1900's for a few individual stations). Also
'record-breaking' for Scotland (& possibly N.Ireland). SUNNIEST March at
Prestwick, Kinloss and Aberdeen since at least 1951. At Eskdalemuir sunniest
since 1929 and at Paisley Observatory since 1894 (Met Office). (Also a DRY
month).
> Apr: Also well-above average SUNSHINE values across the UK, though no
individual records broken.
2. The abundance of SUNSHINE coincided with a lack of RAINFALL during the
months of February to April: averaged over the whole UK something like 65% of
"expectations" for these three months. The strong sunshine and dry
(or drying soils), undoubtedly helped along the way to the events in the
following summer (q.v.); as it was, TEMPERATURE anomalies in March and April
were around +2degC across large areas of the UK, with Scotland particularly
favoured.
2003 (June-August/summer): EXCEPTIONAL WARMTH ACROSS UK - RECORDS
TUMBLE
1. 1. On the 10th August, 2003, the 'all-time' UK highest TEMPERATURE was set
at Kew (Royal Botanic Gardens) with 38.1degC. ( This beat the previous highest
of 37.1 at Cheltenham on 3rd August, 1990 ). On this day, many stations in the
Greater London/suburban south-east of England reached around 38degC, but some
of the highest values have been questioned: for example, Faversham (Brogdale)
reached 38.5degC, but this is now not used due to problems with over-sheltering
of the site. Gravesend also reached 38.1 (as above), but it too is suspect:
amongst others (accepted) are: Aldenham School & Heathrow/37.9,
Wisley/37.8, Northolt/37.7, St. James's Park & London Weather Centre/37.6
and Greenwich Observatory 37.5degC. This day's WARMTH extended into the East
Midlands/Lincolnshire to the north and down across Wessex/Central southern
England.
2. The period 3rd to 12th August was notably WARM, with many records broken.
MAXIMA achieved or exceeded 30degC somewhere or other for all 10 days, and on
6th, 9th and 10th, 35degC was reached/exceeded. On the 9th August, Greycrook
(Scottish Borders) achieved 32.9degC, a new "all-time" Scottish
record for any month [ which beat 32.8degC at Dumfries 2nd July, 1908: this may
have been a degF value converted ]. On the Channel Islands, the day maximum
TEMPERATURE at St.Louis/St.Helier observatory was 36.0degC: this was a new
record for the site, AND for the Channel Islands as a group (in a record since
1894). In addition, many high NIGHT-TIME MINIMA were recorded. Guernsey airport
had a minimum of 23.7degC and St. Mawgan 23.1degC both overnight 4th/5th
August, and both long-term local records.
3. Looking at the SUMMER overall, and only at CET values, the overall anomaly
was +1.6deg (on 1971-2000 values), and is regarded (at the time) as the
fourth-WARMEST in that record. June was the WARMEST since 1976, and August
specifically was in the 'top-5' of all-time warm so-named months, and in the
top-dozen or so 'all-month' warm ones. Not necessarily DRY, with near-average
or above-average rainfall June and July, but August again was notably DRY: the
EWP anomaly was around 27% and again was in the 'top-5' of dry so-named months.
Turning to Scotland, June and July was one of the WARMEST such pairings in the
past 100 years (warmest since 1961), and as August anomaly was +2.0degC, I am
sure that the summer overall north of the border was close to record-breaking.
4. By the end of August, 2003, the overall year-so-far anomaly was running at
around +1.5degC (depending upon which base-set you use). Also, it was announced
in 2004 that the period March to August, 2003 was the WARMEST such period in
the CET record (starts 1659) [RMetS/'Weather'/MetO-Hadley].
5. According to a 'news item' in the April issue of 'Weather' (RMetS), the
University of Berne stated that summer 2003 was "very likely" to be
the HOTTEST since 1500 over Europe as a whole - probably by a 'wide
margin'; major increase in rate of recession of Swiss glaciers.
2003 (August/September):
1. Using the EWP series, the total precipitation for these two months was 56mm,
the second-lowest in the series which began in 1766. (The driest such period
was in 1959 with 46mm).
2003 (10th August): CARLTON-IN-CLEVELAND INTENSE STORM
1. On the 10th August (Sunday), when the 'all-time' UK highest temperature was
being set (see elsewhere), a very INTENSE RAIN-STORM occurred at
Carlton-in-Cleveland (North Yorkshire) when 47mm fell in 12 minutes (46mm in
10min) starting at 0935GMT. The storm was accompanied by a SEVERE SQUALL, HAIL
up to 2 cm diameter and a 9degC drop in TEMPERATURE. There was major DISRUPTION
across the North Yorkshire/NE England region, with many roads FLOODED,
buildings DAMAGED/FLOODED and some trees blown over. The usual crop of power
cuts and a lot of DAMAGE to buildings and cars due to the HAIL. Many vessels
offshore Teesmouth were caught in the SQUALLS, with 2 fishermen being found
dead after the storm had passed. This storm rates as one of the most intense
DOWNPOURS ever to be recorded (and accepted) in the British Isles.
(source = Royal Met.Soc/'Weather')
2003 (November):
1. The daytime MAXIMUM TEMPERATURE of 20.2degC on the 7th November, 2003 at
Lochcarron (Wester Ross) was the highest in Scotland since 1946. According to
Eden (RMetS/WxLog) 'Before this year [2003], November maxima of 20degC or more
in the UK had occurred only in 1906, 1938, 1946 & 1997'.
2003 (Autumn):
1. The three-month total (September, October and November) SUNSHINE total at
Heathrow airport (to the west of London) was 456hr. This easily exceeded the
total of 423hr set in 1997 (q.v.) and this autumn was probably the SUNNIEST
such across London and the Home Counties for at least 50yr.
2003 (Annual): WARM/SUNNY & DRY - AS MET OFFICE LEAVES
BRACKNELL!
1. TEMPERATURES: well above average, particularly using DAY-TIME MAXIMA.
According to the Met Office, it was the WARMEST year in Scotland since at least
1961, with an average TEMPERATURE of 8.3degC. The highest UK (known) daytime
MAXIMUM TEMPERATURE was recorded in August (q.v.).
> Using the Central England Temperature record, with a value of 10.5degC, it
was in the 'top-10' WARMEST years, with an anomaly (re: 1971-2000 dataset) of
+0.8degC. [for the whole earth, the THIRD WARMEST year (in series from 1861).]
2. SUNSHINE: abundant SUNSHINE was a feature across the British Isles
(c.f. 1959, the year the Meteorological Office began it's HQ building in
Bracknell). In the composite record since 1961 (for England), with 1777hr, it
was easily the SUNNIEST over the past 40-odd years. Similarly in Scotland, the
composite sunshine record placed 2003 as the SUNNIEST for that nation over a
similar period. Several sites with long-running records (though of the
Cambell-Stokes variety), recorded their SUNNIEST year on record. Notable
amongst these are Weymouth (2113h/start 1895), Malvern (1776h/start 1929) &
Nairn (1552h/start 1931). More than 2000h of SUNSHINE was recorded from Dorset
to Suffolk as well as in the Channel Islands. According to the 'News' section
of 'Weather' for March, 2003 .. "the fact that 2000 hours appears to have
been reached in several inland areas of south-east England does appear to be
unprecedented ..". (RMetS/'Weather')
3. PRECIPITATION: Using the England & Wales (EWP) precipitation
series, the February to October 2003 total was the second-lowest, after 1959,
since 1921 (R.Met.Soc/'Weather'). Water resources were apparently reasonable
due to the high rainfall winter 2002/2003. However, river-flow was well down by
late autumn 2003. (A WET end to November helped the situation):
> In the Kew Observatory series (begins 1697, ends 1980 - extended using
local sources), this period (February to October) was the second DRIEST, beaten
only by 1921.
> For the YEAR, the EWP ended up 761mm (83% 1961-90 LTA), and this total was
only beaten by 7 other years since 1900 (specifically, 2003 was the DRIEST year
since 1975). However, for the entire series (since 1766) 2003 doesn't even
appear in the 'top-10' of DRY years.
2004 (February):
1. Notably WARM at the beginning of the month; Using the CET daily series, both
the night 3rd/4th & the day 4th produced the highest CET (areal mean)
February values for the respective data-sets (minimum since 1878, maximum since
1772). The MINIMUM value in particular beat the previous value (10.3degC)
handsomely. On the 4th, the HIGHEST MAXIMUM recorded was 17.9degC at Gravesend
(Kent), with many values 16 or 17 across the Midlands, East Anglia & SE of
England. However note that these values are NOT records for either February, or
the first-third of that month, (but the Gravesend value is a record - at this
time - for the first week of February). According to Philip Eden
(RMetS/'Weather Log':.. " as measured by the CET, the first half of the
month was the warmest, alongside 2002, since before 1869 ..."
2. Exceptionally SUNNY in Northern Ireland & the Isle of Man. Although
using different types of recorder, it may have been the SUNNIEST February in
these areas for over 50 years, and in the case of Belfast, perhaps since 1906.
3. The last two days of January and the first four of February 2004 was an
exceptionally WET period across Snowdonia. At Capel Curig, 417mm was recorded
over these six days. This led to severe FLOODING in parts of Wales, most
especially in the north. Andrew Sibley ('Weather'/RMetS: Feb. 2005) reports
that in the 24hr period from 1900GMT on 2nd February until 1900GMT on 3rd
February, 169.2mm of rainfall was recorded at Capel Curig. As a result of the
high RAINFALL, the banks of the River Conwy broke, and the adjacent railway
line carrying services between Llandudno (North Wales coast) and Blaenau
Ffestiniog, Gwynedd was severely DAMAGED and put out of action for many months.
2004 (August): THE BOSCASTLE STORM
1. On the 16th, TORRENTIAL RAINFALL fell on the headwaters of the two rivers
that drain (in combination as the R. Valency) through Boscastle (N.Cornwall).
The highest (24hr) rainfall for this event is 200.4mm at Otterham (nr.
Boscastle), which fell in under 5 hours. At Lesnewth (also nr. Boscastle),
85.7mm fell in just one hour at the height of the storm (actually a series of
heavy rain-producing cells). An estimate (radar and other evidence) has
been made that at least 250mm fell from the storm-complex over Hendraburnick
Down, from where many local rivers flow. Much DAMAGE was done in the town to
buildings, bridges & vehicles - many of the latter being swept out into the
harbour. All boats in the harbour were destroyed (or otherwise lost to the
sea). No-one was killed. FLOODING also occurred in other parts of N.Cornwall,
e.g. Crackington Haven (where structural damage also evident) and Camelford.
[for more on this see S Burt, 'Weather' / RMetS, August 2005.]
2. For August 2004, in the EWP series (since 1766), it was the fifth WETTEST
so-named month. The total was 157mm, or approx. 220% of LTA. Some areas were
even wetter (see above & below), and Leuchars (Fife) recorded 212mm of
RAIN, representing over 340% of LTA. However, it was drier in parts of the
southeast of England & the north of Scotland.
2004 (Summer):
1. With the JET-STREAM often a long way south (for a NE Atlantic summer), it
was very unsettled & often WET across the British Isles. It was
particularly WET across the English Midlands, northern & eastern England
& parts of Scotland - some places had well over double August RAINFALL, for
example the anomaly for Lowestoft was 294% and for Leuchars (Fife), the total
of 212mm represented ~340% of LTA. Earlier, during June, a notably DEEP
DEPRESSION (for June) moved across the middle of these islands (from west to
east), bringing STRONG WINDS and a central PRESSURE of 982mbar - this equals
the lowest value for England and Wales for June in at least 100 years.
2004 (Annual): ANOTHER WARM YEAR
1. The Central England Temperature (CET) was: 10.5degC. This places it inside
the 'top-10' of warmest years in the all-time list. By the mean annual MINIMUM
TEMPERATURE (CET), this was the warmest by that measure in the series. In the
period 1990 to 2004, 8 of the warmest years in the entire series (since 1659)
have occurred in that 15 year span. (For the globe, with a mean anomaly of
+0.4degC, it was amongst the five WARMEST years since 1861: it is worth noting
that there was NO El Nino event to enhance the warmth).
2. A notably THUNDERY year across lowland England. At Heathrow airport (west
London), a total of 23 days with THUNDER recorded, the highest such annual
figure in their record which began in 1947. Within the SE region of England,
particularly just to the south of London & across Norfolk, some places
recorded up to 30 days with 'thunder heard'.
2005 (January): CARLISLE & WELSH FLOODS
1. Very UNSETTLED first two weeks: although monthly RAINFALL overall was below
average (notably DRY east, south & Midland England), locally in Wales and
NW England, high-intensity RAINFALL over the period 7th - 10th contributed to
SEVERE FLOODING, most notably in North Wales and Carlisle, Cumbria. Over a two
day period covering 7th/8th January, Capel Curig (N.Wales) recorded 184mm and
Keswick (Cumbria) 118mm.
2. Later, on the 11th/12th of the month, a vigorous, very deep DEPRESSION moved
to the NW of Scotland, with HEAVY RAIN/SEVERE GALES (low-level GUSTS up to
90+knots) affecting N. Ireland & W/NW Scotland; there was extensive DAMAGE,
with some people KILLED.
2005 (May):
1. A COLD May. On the night of the 17th / 18th, the TEMPERATURE fell to
-6.3degC at Tulloch Bridge [Lochaber]; according to Philip Eden (usw), this was
the lowest May temperature in the UK since 1982, and possibly the lowest
minimum that late in the year since 1956.
2005 (June):
1. As a DROUGHT continued to affect SE England, Hawnby, on the North York Moors
experienced something like a month's rainfall (~50mm) in around half-an-hour on
the 19th, and 70mm in three hours. Parts of Helmsley and Hawnby (and other
local villages) were severely affected by sudden FLOODING: helicopters had to
be used to rescue people from cars etc., as streams became swollen torrents. No
deaths were recorded, but there were widespread power cuts & property
DAMAGE.
> In the SW of England, near Padstow (Cornwall), another high-intensity,
high-yield RAIN-STORM occurred on the 29th: over a period of about 4 hours, at
St. Merryn, an estimated 75-100mm of RAIN fell in this short period
(Crugmeer, near Padstow recorded 51mm, most of which fell within 75mins); roads
became impassable with motorists trapped in cars. (Eden / RMetS "Weather
Log" & "Weather Eye")
2. Notably CHILLY nights during the first 10 days of the month, with some
stations breaking records during the period for low NIGHT MINIMA. Overall
though, it was a WARM month, at least for England & Wales - for some the
second warmest June since 1976. Across some parts of the lower Thames Valley
(including London), the TEMPERATURE anomaly was around +2degC on the 1971-2000
LTA.
2004/2005 (November - June):
1. A lengthy DRY SPELL for many parts of England & Wales, though
concentrated in it's severity across southern England, from south Cornwall
& far south Devon in the west to much of Hampshire, Surrey, Berkshire, West
Sussex and the London area in the east. In these aforementioned regions,
PRECIPITATION anomalies (wrt 1961-1990 averages) were below 60%. [ By contrast,
NW Scotland had anomalies in excess of 140%, largely due to an excessively WET
winter.] (MetOffice / RMetS / 'Weather').
2005 (July): BIRMINGHAM TORNADO
1. On the 28th, a destructive TORNADO moved across southwestern parts of
Birmingham, leading to a score of injuries (but no deaths) & extensive
DAMAGE to buildings, vehicles, trees etc. (See also: 1931 - June)
2005 (September, October & Autumn):
1. Using the CET series, September 2005 had an anomaly (on 1971-2000 dataset)
of +1.5C, and this placed it just outside the 'top-10' warmest Septembers in
that record (since the 17th century); it was one of four or five warmest
such-named months over the previous 100 years. October was remarkably WARM
(particularly by night - see **below), with an anomaly of +2.7C using the CET
value, and thus within the 'top-5' of warmest such-named months (in date order:
1921, 1969, 1995, 2001 & 2005) in the entire record (2nd WARMEST after 2001
using the Hadley figures). (** for a cluster of stations from the NW Midlands
down to the south coast, the overall anomaly for mean minima was well in excess
of +3C). October was however distinctly disappointing as regards SUNSHINE.
> Combining September & October in the CET record, it was amongst the
WARMEST such pairing in that series: depending who you take, it could have been
the warmest (vying with 1949 for that honour).
2. Autumn (September, October & November), was by a whisker the WARMEST
such-named season since 1978. The mean CET was 11.5degC (+1.2C anomaly),
rendering it one of the 5 or 6 WARMEST Autumns in the past two centuries, and
if it was not for the very cold second half of November, it might have been the
'all-time' warmest autumn over England & Wales.
2005 (November & December):
1. According to Philip Eden, "it was the SUNNIEST November, averaged over
England & Wales, since before 1881, and new station records were posted at
more than 20 sites in eastern, central & southern England". In
particular, an excess over long-term mean values of 150% or more occurred
widely across the north Midlands & N. England, with pockets similarly
favoured across SE England. Waddington, near Lincoln (Lincolnshire) had 111 hr,
which represented 164% of the LTA. The excess of SUNSHINE continued through
much of December 2005, with anomalies locally well in excess of 170%. For
England and Wales, it is thought to have been the fourth SUNNIEST December
since the late 19th century: Philip Eden writes that it was the SUNNIEST
November & December since modern records began.
2005 (December): BUNCEFIELD OIL-DEPOT FIRE
1. Just after 0600 GMT on Sunday, 11th December, a series of large explosions
occurred at an oil-storage depot (Buncefield) on the outskirts of Hemel
Hempstead, Hertfordshire. The resultant fire was regarded as the most intense /
largest in western Europe since the end of the Second World War. The plume of
smoke from the fire affected some areas well away from the source, reducing
solar radiation significantly, until the fire was extinguished late the
following day. Dispersion of the smoke plume was slow, as the dominant pressure
pattern was anticyclonic.
2005 (Annual):
1. According to WMO members, 2005 was the second WARMEST year on record, and is
likely to be amongst the four or five WARMEST years since 1861. (1998 is the
warmest q.v.). However, according to the US Climate Data Center, 2005 may have
been the (equal) WARMEST, with 1998. The fact that this was a
'near-record' year for warmth is doubly interesting, as there was NO strong El
Nino event, as there was in 1998.
> By the CET record, the anomaly was around +0.7C (wrt 1971-2000 series, or
+0.9C wrt 1961-1990 standard), and placed 2005 within the 'top-10' of warmest
years. Of the 10 years 1996-2005, 8 had all-year anomalies of greater than
+0.5C. The consistent WARMTH of the past decade is also reflected in series
covering Scotland & Northern Ireland. Whichever way you look at it, it was
an exceptionally warm year, following a continuing upward curve in national
TEMPERATURES.
2004-2006 (November 2004-January 2006):
1. According to the Met Office (as reported in 'Weather', March 2006), the DRY
spell over SE & Central Southern England over this period represented the
DRIEST November-January period since 1920-22. However, this anomaly is focussed
in a rather narrow strip from Hampshire to Kent.
2006 (June/July):
1. June & July 2006, taken together, were notably WARM & very SUNNY.
There was also a lack of RAINFALL, at least over large parts of England &
Wales. Much of Britain was exceptionally DRY until the last week of June, 2006.
By the EWP series (MetOffice / Hadley Centre), the value of 21 mm represented
~31% of the long-term average, and provisionally it was the 10th DRIEST June in
that series. Only 3mm of rain fell at St. Catherine's Point (IoW) & 4mm at
Benson (Oxfordshire) [Philip Eden]. According to COL (bulletin), a large area
of the Midlands, north & west Home Counties & parts of East Anglia had
<25% of average, with a small area around Bedfordshire / north
Buckinghamshire ~10%.
2. TEMPERATURE: Using the Central England Temperature (MetO/Hadley) series,
these two months together were in the 'top-3' for WARMTH in that series (begins
1659), alongside 1826 & 1976. By mean MAXIMUM TEMPERATURE, it was arguably
the warmest such pairing for over a century. Specifically, June 2006 was
probably the WARMEST June across a large part of the British Isles since 1976
(a memorable summer), with anomalies typically +2C across much of England &
Wales. Looking only at mean MAXIMUM TEMPERATURES, then anomalies exceeding +3C
were reported from central southern & southeast England. July was also a
very WARM month: the provisional CET value of 19.7degC places it as the WARMEST
July (and WARMEST any-named month) in this long established record.
There were two HOT spells; one at the beginning of the month, and one from 16th
- 19th, and on this latter date, the all-time (known/accepted) July British
Isles TEMPERATURE record fell; 36.5degC was reported from Wisley, Surrey,
beating the previous (accepted) highest of 35.9degC at Cheltenham in 1976.
3. Following a very SUNNY June across much of Wales, central & southern
England, July saw many long-standing SUNSHINE records broken across a wide
swathe of Britain, from south & southeast England to the central lowlands
of Scotland. According to Philip Eden, this was (for England & Wales)
'easily the SUNNIEST July since records began in 1881 .. and probably also the
SUNNIEST calendar month of any name on record.' Specifically for southeastern
England, with total SUNSHINE in the range 300-350 hours, it was probably on a
par with the very sunny month of July 1911 in this region, though comparison is
difficult due to changes in instrumentation used.
2006 (Summer):
1. Although PRECIPITATION averaged over the country was below average (for the
England & Wales series ~76% of 1961-1990 average & for Scotland ~82%),
the summer was notable for two dramatic STORMS:
> On the 26th June, showers / THUNDERSTORMS readily formed, and at Penzance
(Cornwall), aided by sea-breeze convergence, 82.1mm of RAIN was recorded in the
24hr from 0600GMT on the 26th (mostly in the evening & early part of the
night), leading to much FLOODING in the area.('Weather', August 2006 &
others)
> On the 13th August, THUNDERY RAIN developed along a marked line of
convergence which stretched from East Anglia to Hampshire. By the late
afternoon / early evening of the 13th, some places within this zone had at
least 80mm of rain (within roughly 6 hours), with isolated instances of over
100mm of RAIN: NE Hampshire & NW Surrey were particularly badly affected,
with the local railway line closed for four days, properties FLOODED & much
disruption to road transport.
> In addition, East Anglia had a particularly WET August, with a range of
%ages of 170% across Norfolk & 250% for Suffolk.
2. According to the Met Office, the three-month summer of June, July &
August was one of the WARMEST on record for the UK, with an anomaly of roughly
+1.5degC on the long-term mean. For the CET domain specifically, with a
(provisional) value of 17.2 (+1.6C on 71-00 mean), it was ranked fifth in the
whole series. It was also SUNNY and DRY (see 1. above). [ The
WARMTH was a feature for a wide area of continental Europe, with anomalies
generally +1 to +2degC, and in parts of northern Europe, the anomaly was up to
+4degC.]
2006 (Autumn): RECORD-BREAKING WARMTH
1. This was, both by the CET and UK-wide record, easily the WARMEST Autumn in
their respective series (for the CET since 1659) - the WARMTH was spread out
across all three autumn months with September setting a new record (see below);
for the CET, the value was 12.6degC. From COL records, the warmth was most
evident (within the British Isles) across SE and Central Southern England &
East Anglia, with an anomaly (wrt 1971-2000 means) of +2.6C. (Previous warmest
Autumns in the CET series were 1730 & 1731; the figure recorded for 2006
outstripped those for these 'ancient' years by a considerable amount - around
0.8C!).
[ The exceptional warmth was a feature of virtually the whole
of Europe - only Greece, the southern Balkans & Turkey-in-Europe missing
out. A broad swathe of anomalies >+3C stretched from SW France, across all
of Germany & the Low Countries to the Czech Republic & the Baltic
States. ]
2. September 2006, was the WARMEST September in the CET record: The
(provisional) figure of 16.8degC, is 3.1C above the 1971-2000 LTA, beating the
previous 'record-breaker' in 1729. Using a wider measure covering the
whole of the British Isles, it was the WARMEST September for at least
100 years. (Met O / COL). (Also worthy of note was that owing to the fact that
August 2006 was 'around average' as regards temperature, September was
considerably warmer (& also SUNNIER) than this nominally summer month, by
as much as 1C in some eastern areas of England. According to Bob Prichard /
letters COL / taking sunshine AND warmth together, this September was
unparalleled in the modern record.)
3. October 2006: an EXCEPTIONALLY WARM month (again!): The CET (provisional)
value was 13.0degC, representing an anomaly (wrt 1971-2000) of +2.6C, with
anomalies locally across southern England of +3.5degC. The WARMTH was again (as
for September) experienced across the greater part of the UK, though October
2005 was technically warmer for England & Wales. This October lies in the
'top-5' of warm such-named months in the series which began in 1659.
4. For the extended period April - October, 2006, it was the WARMEST
thus-defined period in the CET record.
5. It was also a WET Autumn in central-southern England, the south, west &
northern Home Counties & parts of East Anglia, together with many populated
parts of Scotland - in the former case, this was important as it offset a
DROUGHT that had triggered water supply restrictions across parts of SE
Britain; in the latter case it 'set the scene' for some serious FLOODING during
the subsequent winter season.
2006 (December):
1. The north-west London district of Kensal Rise experienced a damaging TORNADO
(T4 at least, perhaps T5) on the 7th December, 2006. A small but intense line
of THUNDERY downpours moved quickly east across southern England, reaching
London around 11GMT. It produced gusty winds, heavy RAIN, HAIL & notable
'day-darkness'. ('Weather' Jan 2007 & TORRO).
2006 (Annual): WARMEST-EVER YEAR IN THE CET RECORD
1. 2006 is the WARMEST year in the CET record (began 1659), with a value of
10.8degC. This represents an anomaly of ~ +1.3C. The previous warmest
years were 1999 & 1990. Using a wider measure covering the whole of the UK
confirms that this was the WARMEST year over that domain since at least 1914
(previous warmest across the whole-UK was 2003).
2006/2007 (Winter):
1. Exceptionally MILD. Using the CET record, for the three months DJF=6.4degC
[anomaly +1.9C on 1971-2000 means], the WARMEST winter by this measure since
1989 (6.5degC). In the entire series (since 1659), this was the fourth warmest
winter by this measure. Much of lowland England had an anomaly on MEAN
TEMPERATURE greatly exceeding +2.5C.
2. January was a particularly WARM month. By the CET record, with a value of
7.0degC (+2.8C), this January was the fifth WARMEST such-named month in the
series (began 1659); it came behind: 1796, 1834, 1916 & 1921. According to
Philip Eden (Weather Log/RMetS) " rarely for January, there was not a
single instance of a sub-zero maximum at a low-level site in the UK ".
3. Two points of note: the Glasgow area apparently had it WETTEST December 'on
record' (Bishopton 295mm/222%), whilst at Aberdeen, the SUNSHINE total of 88hr
greatly exceeded the previous December record in 1951. (Philip Eden/Weather
Log/R Met Soc). Across the winter as a whole, according to the Met Office,
large areas of central, west & NW Scotland had PRECIPITATION anomalies
exceeding 150%, with small pockets (including some high population-density
areas in the 'Central Belt'), exceeding 175% of the long-term average.
4. SEVERE GALES caused widespread DISRUPTION and loss of life on the 18th
January, 2007 as a depression tracked eastwards across Scotland & headed
for northern Europe. Like the STORMS of the 3rd January, 1976 and the 25th
January, 1990, it was notable for high GUSTS in central and eastern England (67
knots Heathrow & Northolt) as well on western coasts. In places, it was the
severest GALE since the 'Burn's Day storm' of 1990 or the storm of the 30th
October, 2000. 13 people were known to have been killed on the day in the UK.
('Weather', Feb2007)
2007 (April):
[ According to Philip Eden in 'Weather Log'/R MetS: this was the eleventh most
anticyclonic April in 134 years of records.]
1. Exceptionally WARM, and many areas of the British Isles set new records for
both April maxima and mean TEMPERATURES. Maximum temperature anomalies were at
least 5C above the long-term average over many parts of southern England, with
a local +6C anomaly 'hot-spot' in SE Hampshire / West Sussex. By the CET value
(prov. 11.2°C/+3.1C c.c. 1971-2000 series), it was the WARMEST April since
at least 1659. The previous warmest April was that of 1865, with a value of
10.6degC, so rather than the new record being a few tenths of a degree above
the previous 'record', this year the record was 'smashed' by 0.6C.
2. It was also very DRY, with near-DROUGHT conditions over southeast England,
East Anglia, the East Midlands, Wessex & Lincolnshire: many places here
recorded much less than 5 mm of RAINFALL, with a few spots (i.e
Norfolk/Suffolk, lower Thames Valley & either side Thames Estuary) no more
than 1 mm. From the Royal Met.Soc 'WxLog' data, Lowestoft (Suffolk) &
Hastings (Sussex) did not return measurable rainfall for this month, whilst
Cambridge recorded just 1 mm (2%).
> With an EWP value of 9.5 mm (representing just 15% of the LTA 1971-2000),
it was the 4th DRIEST such-named month in the series (starts 1766): more
impressively, for the south-east of Britain (using the Hadley dataset /
definition), it was probably the equal DRIEST April (with 1912) since at least
1873, with just 2.0 mm of PRECIPITATION.
3. It was also very SUNNY: exceptionally so for the southern half of Britain,
where some stations had their sunniest April on record. According to Philip
Eden (WxLog/RMetSoc), it was the second-SUNNIEST April (after 1893) in a record
that starts in 1881.
2007 (Spring):
1. Spring was the WARMEST in an areal series back to 1914 for the UK &
England and Wales, joint-warmest for Scotland and second-warmest for Northern
Ireland. It was also SUNNY, with anomalies exceeding 125% over most of the UK,
and around 140% in a zone extending from the Isle-of-Wight, through Hampshire
and east Dorset to much of Berkshire & south Oxfordshire. [Previous warmest
1945.] (Met Office/NCIC as reported in 'Weather', July 2007)
2007 (May, June & July): MAJOR FLOODING EVENTS OVER
ENGLAND
1. This period was exceptionally WET, both as regards the individual months,
and when aggregated. This is the wettest sequence of such months in the EWP
series (see also 1789), with a total EWP value of 415 mm, (approx. 224%
1971-2000 LTA). May, with 121.0 mm (198%) entered the 'top-10' of such-named
months in the series, and June, with 154.7 mm (227%), only narrowly missed out
rising to the top of the list: June 1860 was slightly wetter with a value of
157 mm. July was the WETTEST such-named month since 1888 (but 1988 ran it close
and statistically there was not much to choose between 2007 & 1988).
2. As a result of the heavy & often prolonged RAINFALL, there were many
stories of disruption and DAMAGE during this late spring / early-to-mid summer
period: major events, such as Wimbledon, Glastonbury etc., were affected, as
well as many smaller events around the country. FLOODING attained 'major'
proportions for South & East Yorkshire, the north & west Midlands &
along the Severn & upper Thames valleys. In June, two major rainfall events
between the 13th and the 15th & then again around the 24th/25th led to
major FLOODS affecting communities from the Midlands to South & East
Yorkshire; there was also significant flooding for some counties in Northern
Ireland. The flooding in Yorkshire, particularly near Doncaster & around
Hull & Sheffield, generated headlines in the national & international
press - infrastructure items such as pumping stations were seriously affected,
and many people were unable to return to their homes - estimates suggest at
least a year for full recovery. In July, short-lived flooding affected southern
England, particularly in parts of London, but the major event of this month
occurred across the lower Severn and upper Thames valleys around & in the
days after the 20th: intense RAINFALL produced well in excess of 100 mm
(Pershore / Worcestershire 157 mm), and hundreds of thousands of people were
without fresh water for several days, electricity supply was interrupted &
many were flooded out of their homes. Comparison was made with the March 1947
flooding in the same area - similar in effect, but completely different in
type.
[ NB: the Foot & Mouth outbreak (early August) in Surrey
may have been linked to faulty drainage pipes, and so the abundance of surface
water, possibly contaminated with the virus, could also be linked to this poor
spell of weather.]
2007 (Autumn)
1. Very WARM & notably DRY across Northern Ireland, with an overall
TEMPERATURE anomaly around +2C & many areas experiencing 60% or less of the
long-term (1961-1990) average. In particular, the Province had its
second-WARMEST November in a Met Office series that started in 1914. It was
also a very DRY autumn in south & west Wales and the far SW of England.
(Met Office, COL & RMetS/Weather log)
2007 (Annual)
1. According to the annual summary on the Met Éireann web site, it was
the WARMEST year in the respective records at Valentia Observatory (1892) and
Malin Head (1885). For Ireland as a whole, the TEMPERATURE anomaly was just
over +1C; for Northern Ireland, the Met Office(UK) note that in a series
starting in 1914, it was the WARMEST year. By the longer-period CET series,
provisionally 2007 was equal tenth (with 2004 & 1959) in that long series
[started 1659].
2008 (January)
1. Another EXCEPTIONALLY WARM January / winter month. With a CET of 6.6degC
(+2.4C on 71-00 LTA), it was only 0.4C cooler than the previous January [ which
was 5th warmest such-named month q.v. ], and places it (provisionally) at equal
9th warmest January in that series. The WARMTH was most evident across Wales
& England, with large areas of +3C anomaly across central & eastern
England. It is interesting to note that the mean low-level flow (isobaric) was
W or WSW, and thus not bringing air from the 'deep', sub-tropical south, but
from the mid-latitudes of the North Atlantic.
2. RAINFALL was well above average across most of the country (UK) with pockets
of >=200% on LTA scattered about from 'Wessex', across much of the north of
England & around the Forth & Tay estuaries. (COL) According to Eden
(RMetS/WxLog), 'new records were set in the Edinburgh, Glasgow & Belfast
districts'. Using the EWP series, this January was within the 'top-10' WETTEST
such-named months.
2008 (February)
1. SUNSHINE was remarkably high averaged over the month, especially across
England, Wales, the Channel Islands, much of Northern Ireland & east and
northeast Scotland. Large areas of lowland central & SE England had over
200% of LTA, and according to the Met Office, many parts of England & Wales
had their SUNNIEST February since at least 1929 (start of consistent series).
According to Philip Eden (WxLog/RMetS), it was 'substantially SUNNIER than
previous sunny Februarys in 1891, 1949, 1970 & 1988'. It was also a WARM
month, mainly due to mean MAXIMA being some 2 to 3C above the LTA.
