Is SST's continue to rise we won't see cold spells in the UK. You don't even
need to be a Scientist to work that one out. --------------------------------------------------------- |

... But Richard, isn't that exactly why Greece is seeing such weather? Maybe I misread your post.. do you mean long-lived cold spells are possible in the UK or other parts of the World? Just in case some things have been misunderstood, as far as Greece is concerned: Athens has seen an *average* number of snow days this winter -until now. Figures below are for SE Athens, alt 150m amsl: December 2003: 2 January 2004: 4 February 2004: 3 (last one was today) The low temperatures helped snow stay on the ground a bit longer than it does on average, but we had by no means record low temperatures, except for the lee coastline of Athens. The track of lows during *this* winter has caused more snow on the islands. This, ofcourse, is outweighed by the lack of snow in northern continental Greece, apart from the mountainous areas, as some areas that remain traditionally under a snow cover for quite some days in winter have received much less snow than average -thusfar. The few data above do not imply that the climate here has gotten any colder. 2001, 2002 and 2003 have been a bit more continental (in terms of annual temperature ranges); this means that low temperatures in winter time continue to be proceeded by high temperatures in the summer. All the best, Yannis, SE Athens |

![]() "Waghorn" wrote in message . I wld think the latest IPCC report sets out the basic consensus understanding pretty well- http://www.grida.no/climate/ipcc_tar/wg1/index.htm Consensus there may be, but I'm not convinced that there's much understanding. My understanding is that that at least in the near to medium term GW is likely to manifest itself thro changes in natural modes of climate variabilty eg NAO/AO (putting aside the possibility of rapid climate change via eg THC flips,Pace McDonald!).If the trend for the NAO overall becomes more +ve ,ie more zonal,this does not preclude years or even 10s of years,when a -ve NAO is possible,blocking is likely and cold air outbreaks can occur. Absolutely. But that is, nonetheless, an awfully big "if". It shld be remembered that variability occurs on a wide variety of time scales,quite naturally,AGW aside. Including scales which we can only scratch the surface of, given the limitations of proxy data. pe |

If the broadscale circulation is
stuck in a groove that brings persistent relatively warm SW'lies to our corner of Europe then it is virtually certain the somewhere about half a wavelength downstream will be getting weather persistently colder than average. Some clear-headed logic! We know our winters have been warmer in the last 15 yrs or so, but are figures available for other mid-latitude places, eg America, Russia which might show how their winters have changed, if at all, in a similar period? This comparison could tell us a lot. I'd do it myself but am not quite sure where to look. Tudor Hughes, Warlingham, Surrey |

While it might well decrease I don't think that even the most pessimistic predictions of global warming would result in Alpine snow completely disappearing in the next 100 years. Norman.

Hi Richard,
No problem, I'm happy. All I'll say is some people in this newsgroup haven't been outside\looked out the window much in the last 15 years! , or are extremely blinkered. (probably the latter). Yes, a switch has been flicked in my humble opinion. Don't worry, I'll remind you so in 5-10 years time if you finally have a change of heart. And if I'm wrong, which I dearly hope I am, slaughter me, please. BTW, I accept I'm just guessing. I remember 5 years ago when I first followed this newsgroup.. people were very optimistic then, turning a blind eye to GW, turning a blind eye to anything out of the ordinary... well how things have changed. Stock up on those Shorts and T-Shirts, 'cause woudn't surprise me if summer conditions occur in February within 15 years time. I'm looking to the future... lots of south coast business opportunities I feel. ![]() ---------------------------------------------------------- Well, either way - please get over it and cheer up. There's always a holiday in the Alps if things aren't cold enough here and you *really* want snow!! Richard |

This comparison could tell us a lot. I'd do it myself but am not quite sure where to look. My subjective impression is that there seems to have been a tendency for colder than average winters in recent years in the Turkey/Balkans region, with the favoured location of the Highs that bring us south-westerlies bringing them northerlies or north-easterlies. But I could very easily be wrong. -- John Hall Weep not for little Leonie Abducted by a French Marquis! Though loss of honour was a wrench Just think how it's improved her French.
