THE GUARDIAN (13/June): “ Washout summers. Flash floods. Freezing winters. Snow in May. Droughts. There is a growing sense that something is happening to our weather. But is it simply down to natural variability, or is climate change to blame?

To try to answer the question the Met Office is hosting an unprecedented meeting of climate scientists and meteorologists next week to debate the possible causes of the UK 's "disappointing" weather over recent years, the Guardian has learned.  …

The "roundtable workshop" will attempt to outline the "dynamical drivers of the cold spring of 2013", but attendees are expected also to debate the "disappointing summers of the last seven years".

Our first comment today will focus on the dynamical drivers in recent weeks, which had been sub cold in Western Europe and contributed to the extreme flood in Central Europe during the last two weeks.

Once Met-Off. has something to say about other disappointing summers recently, it will be recorded accordingly.

 

Cold Spring of 2013?
Only to reckon the NE-Atlantic and North Sea !

Since early March 2013 the northeast Atlantic and the North Sea are unusual cold [HERE]. The extreme anomaly continued in April [HERE]. During both months the Baltic Sea remained below average sea water temperatures (SST), but less severe as in the North Sea . That changed in early May [HERE]. Since then extreme difference established between the two seas during the last four weeks. The North Sea remained cold. The Baltic Sea SST rose well above normal (Fig. 3-6).  Also SST west and south of the UK remained low. A main culprit in an unpleasant spring is too low SST around Great Britain .

The relevant SST for Western Europe is shown in Fig. 7-9.

Daily Mail - mailonline /UK on 16. June 2013:

“Madness of the Met Office Summit meeting to find out why our weather is... normal”
The matter gets curious writes David Rose (excerpts): 
___”As of lunchtime yesterday, the Met Office wasn’t at all sure how Britain ’s weather would turn out today. According to a spokesman, some of its computer models were predicting ‘a rather miserable day for some southern areas’. Others, however, suggested it would be ‘fine and bright’.
‘Sometimes the atmosphere can provide a real challenge for forecasters,’ the spokesman admitted wearily. The problem right now, apparently, is a phenomenon known as a ‘trough disruption’, a common type of westerly weather whose course both computers and human beings find hard to predict. Still, the signs were that by the end of the week, temperatures would be normal for June, at about 20C. Looking further ahead, there were likely to be both some downpours and some nice, sunny days.
‘It’s what you’d term typically British weather and far from a wash-out,’ the spokesman concluded, adding that although summer only began officially on June 1, so far it has been relatively warm, a few cool days last week notwithstanding. “
