Some notable months and seasons since 2006

Recommended Posts

If we start from 1st January 2006, so in the last 8 years, here are some amazing stats that have occurred that have either broken or got in the top 10 of long standing records such as the CET, rainfall series. I may have missed out one or two and it doesn't include such things as the highest maximum ever recorded in October etc.

If my calculations are right, I reckon about 1 in 5 months have been in the top 10 for one or more reasons.

These are long standing records, CET goes back to 1659, rainfall series to 1772

Notable that the word 'warmest' is appearing an awful lot more than 'coldest'.

You can also add that July 2013 was the 10th warmest on record for the CET. 

 

Another CET statistic that has been made in recent years is that Winter 2010-11 saw either the 3rd or 4th largest increase in the CET from December to January on record, and also the largest increase in the CET from December to February on record.  That is a winter in the records for reasons other than all those on your list.

Shocking that March 2013, despite feeling so unseasonable at the time, was only the 13th coldest. Thats compared to all the warm months (5 months either warmest on secord or second warmest since 2006). Just shows that despite the increase in cooler than average months recently, weve seen very few extrordinarily cold months, except Dec 2010 of course.

I think any time you have an anomalous month you'll find anomalous month to month changes. I'm not sure if the number of them is unique to now, or whether there are just so many to choose from, such as the largest March to July increase on record (2013), the smallest April to June increase on record (2011), the largest October to December decrease on record (2010), etc.

I have noted a couple of times,and it is for my local area and I do not know about in the cet zone that with the exception of 1978/1979,you have to go back to the 60s to find a November to may period with more air frosts than that of 2012/2013,beating 2010 by a country mile!

What winter 2010-11 was remarkable for was that although it saw an extraordinarily cold spell at the start it certainly didn't go on to see a winter which remained cold overall.  In fact after Dec 27th winter 2010-11 saw an overall CET around 4.9 or 5.0 for the rest of the winter - which clearly shows that what followed after the severe cold spell was over was certainly nothing special, with the February in particular being very dissapointing.  It felt as if winter had blown itself out.

 

The early part of winter 1981-82 also saw an extraordinarily cold spell, a bit like Dec 2010, but that didn't go on to see a winter in which sustained cold held sway.  Winter 1950-51 also saw a cold December, but the rest of the winter appears to have been pretty average.

 

To find the last good example of a winter seeing an extraordinarily cold spell in its early part (pre Xmas) that went on to see a winter in which sustained cold held sway, we have to go back to 1878-79, which was a pretty good example, Dec 1878 (-0.3 CET), Jan 1879 (-0.7 CET), and Feb 1879 (3.1 CET), not as cold as the first two months of the winter, though still quite cold by today's standards.  Winter 1890-91 wasn't that bad, though Feb 1891 was fairly average, but March remained cold.

Well it looks as though it is the wettest January now.

Just look at those that top the list

Warmest spring: 2006

Warmest and sunniest July: 2006

Warmest September: 2006

Warmest autumn: 2006

Sunniest November: 2006

Warmest April: 2007 until broken

Sunniest February: 2008

Warmest and sunniest April: 2011

Warmest spring: 2011

Wettest April: 2012

Wettest June: 2012

Wettest January: 2014

It says to me in the last 8 years, weather patterns have been getting into "ruts" or locked in for lengthy periods of time in order for these records to fall.

Not only that but apart from December 2010 the cold accolades are considerably more feeble than the warm accolades.

 

I think any time you have an anomalous month you'll find anomalous month to month changes. I'm not sure if the number of them is unique to now, or whether there are just so many to choose from, such as the largest March to July increase on record (2013), the smallest April to June increase on record (2011), the largest October to December decrease on record (2010), etc.

To add to this the increase from December 2010 to both March 2011, April 2011 and May 2011 was also the largest on record and the increase from April 2011 to both July 2011 and August 2011 was also the smallest on record.  The decrease from July 2011 to both October 2011 and November 2011 was the smallest on record.  Also the decrease from August 2011 to both October 2011 and November 2011 was also the smallest on record.  The increase from Spring 2011 to Summer 2011 was the smallest on record and the decrease from Summer 2011 to Autumn 2011 was also the smallest on record.  In reverse the decrease from July 2010 to December 2010 was the largest on record.  The increase from the first half of 2013 to the second half of 2013 was the largest on record. 

 

I have noted a couple of times, and it is for my local area and I do not know about in the cet zone that with the exception of 1978/1979,you have to go back to the 60s to find a November to may period with more air frosts than that of 2012/2013,beating 2010 by a country mile!

2013 also has the distinction for having the greatest amount of CET frosts in the first half of the year but also the smallest amount of CET frosts in the second half of the year.

 

In fact after Dec 27th winter 2010-11 saw an overall CET around 4.9 or 5.0 for the rest of the winter - which clearly shows that what followed after the severe cold spell was over was certainly nothing special, with the February in particular being very disappointing.  It felt as if winter had blown itself out.

Indeed in the last 8 years there are many occasions when a portent and/or sustained cold spell has "Blown itself out" or even "blowtorched itself out" (That's a new term for the Net-Weather Urban Dictionary!Posted Image) to be replaced with ridiculous and/or sustained mild spells such as late March 2006, mid April 2006, late April 2008, late July 2008, early November 2008, mid February 2009, late June 2009, mid March 2010, late May 2010, early January 2011, early February 2011, early September 2011, mid February 2012, mid May 2012, late July 2012, early November 2012, mid December 2012, early July 2013, late September 2013 and late November 2013.

So what do we blame this stuff on?

The jet stream in recent years has been described as "drunk" by some scientists. It's ridges and troughs becoming more extended, and slower moving, leading to stuck weather patterns, blocking and extreme weather. Nobody can say for certain what the cause is, but there are a few theories floating around.

 

A interesting piece about the jet stream

More of the same this year.

When you read papers on the grand solar minimums and their effect on climate in Europe, there are numerous references to this type of pattern where weather gets locked in for seasons and the effects it had on the agricultural and social conditions. The popular headline seems to always be the cold winters - all seasons seemed to have extremes, this being borne out by records of wine making and wheat price fluctuations. I'm sure the local wars were also a related issue; recently the variability in weather over just a few hundred miles has been obvious in some of the events listed above - in times of old when one had no global resources to fall back on, it would be tempting to acquire the 'greener' pastures by force.

 

The sun has gone quiet just at the same time as record ice loss is occurring in the Arctic - there's a connection somewhere.

Yes the most notable aspect of the weather in recent years has been the propensity for lengthy spells of very similar conditions, with little variation from week to week and month to month, the jet stream has certainly got stuck into a rut for lengthy periods (the current period is a very extreme example of this), also what has happened on many occasion is the change from one pattern to another has been very abrupt with no slow transitional stages.

 

Where has the classic ridge followed by trough pattern disappeared too? Where have the polar maritime airstreams disappeared too?

 

I have to say this current pattern is very unusual in terms of sheer persistence with no break, I don't recall the BBC ever with confidence saying how the month is likely to pan out at its start.

Isn't it about time we got stuck in a lengthy warm, dry spell during the main summer months! Sick of having perfect conditions in the spring followed by washout summers.

Indeed, since early January it has felt (at least here in North Yorkshire) as if it's been one frontal system almost immediately after another, with polar maritime air struggling to take hold for more than 12-24 hours at a time.  The frequency of sunshine-and-showers days was pretty low considering how "westerly" the month was, and this was also reflected by the lack of sunshine (westerly winter months have a tendency to be sunnier than average to the east of the Pennines, but in January 2014, above-average sunshine was more confined to Lincolnshire and East Anglia and the SE).

 

I recall a similar issue keeping many unsettled spells relatively thunder-free during recent summers- frequent frontal passages preventing bright showery thundery conditions, or plumes of continental air from the south, from establishing for long in between.

 

Isn't it about time we got stuck in a lengthy warm, dry spell during the main summer months! Sick of having perfect conditions in the spring followed by washout summers.

Although we had a long run of wet summers, we did have a lengthy spell of generally dry weather from the beginning of June to the 21st July.  July was also a warm sunny month almost everywhere, and exceptionally so in the west, although June had numerous cool cloudy spells in the east, particularly east Yorkshire, Lincolnshire and East Anglia where sunshine and max temperatures fell slightly short of the average despite a shortage of rainfall.

Top 10 wettest winter now to add to the list. The question is how high it gets up the table.

Wettest winter on record for England and Wales by a margin at that. At least 3rd wettest season on record for England and Wales.February 2014 looks like it could be joining the top 10 wettest February list.

Another statistic for winter 2013-14, whilst although it was slightly less mild overall than 1988-89, 1989-90 and 2006-07, it sets a new record, that for the first time ever since the daily CET record began in 1772, no daily CET value below 3.0*C has been recorded during any of the months of December, January and February.  Prior to the start of December, a daily value of 2.5*C was registered for Nov 23rd 2013, making this so far the coldest day of the "extended winter".  If no day in March beats this, the winter of 2013-14, and even the extended winter of 2013-14, will record the highest daily minimum CET for any winter since the daily record began in 1772.  This just shows where winter 2013-14 stands out in the records for being devoid of anything remotely cold.

Bar September (average) and November 2013 (below average), every month since July 2013 above average.

Suspect winter 2013-2014 will turn out to be a bit of a freak -one off, the absolute lack of any cold synoptics was highly unusual. Just a hunch but suspect we are coming the end of this warm phase which began in July last year.. sods law the end occurring in time for summer.. just my thoughts.

2014 alone

Wettest January on record

7th wettest February on record

Joint 8th warmest April on record

Looks highly likely a top 10 driest September on record to add to this list.

If confirmed that would make at least a third of this year having tended to the extremes.
