Freymodur Sigmundsson, a geophysicist, concluded that the immediate danger was receding and that the lava was flowing along a one kilometre-long fissure and in the darkness binding. The original fear was that the volcano had erupted directly underneath the Eyjafjallajokull glacier." http://www.timesonline.co.uk/tol/new...cle7070239.ece According to NottheMetO, the charts show a significant chance of further eruptions tomorrow afternoon. (WetterZentrale Tuesday afternoon, 23rd March 2010.) A year without summer might be on the cards too, so don't put all your money on the other. |

When I get home from work I will try and find my original post or, if not, I will recreate the analysis. |

Martin,
I've done a quick analysis on the correlation between cold winters since 1940 and the following summer whereby; Winter Average CET 1971-2000 = +4.5c Cold Winter CET = +3.5c Summer Average CET 1971-2000 = +15.6c Below Average Summer CET +15.1c Above Average Summer CET +16.1c Average Summer CET =15.1c =16.1c Of the 23 Winters since 1940 that had an average Central England Temperature of = +3.5c the following Summer turned out to be the following; Below Average = 9 Above Average = 2 Average = 12 This can also be viewed in spreadsheet form by clicking on the following link http://i393.photobucket.com/albums/p...sSince1940.jpg Source data taken from the Met Officehttp://hadobs.metoffice.com/hadcet/data/download.html Conclusion, I would go for a cooler or average summer, NOT a BBQ summer this year. |

They also managed to get a short piece on the front page of the Telegraph. I suppose that because most newspaper people know next to nothing about the weather, they accept whatever guff they are fed in press releases at face value. -- John Hall "Acting is merely the art of keeping a large group of people from coughing."

Because of the warming trend in our climate over the last 30-40 years, you'd expect a lot of years in the 1940s to 1960s to have both winters and summers that were cool by the standards of 1971-2000, so that for those cold winters mostly to be followed by cold summers would not be surprising. What happens if either (1) you only look at cold winters since 1971 or (2) you use the CET of all years since 1940 in determining your categories for winters and summers? -- John Hall "Acting is merely the art of keeping a large group of people from coughing."

I'd say from the data presented it could be a cooler or an average or an above average summer. Unless you can isolate the reasons why they are not all below or above a certain line, then you have to suspect there is a step missing in the projection. Sorry about that. I am not saying that you can't find it. I am just telling you to look again. |
