I'm not writing off the winter, but i don't pretend that i'll know what
it'll be doing for the next four months !! Are things boring at the moment or what? Folks on TWO have resorted to posts like "don't forget The Day After Tomorrow is being shown tonight" !! Yeah right, based on a book "The Coming Global Superstorm" by Art Bell & Whitley Streiber (remember him? His book about being abducted by aliens many years ago) These fellas are not about light entertainment, they are serious. If you've heard them on the radio, you will know they 100 percent believe in what they say Every storm, hurricane and tornado that occurs is used as a reason for these people to get back on the airwaves and proclaim "look see, it's really happening" Here's a review on another book written by Art Bell http://www.csicop.org/sb/9712/baker.html From some of the doom-mongering i've been reading in the press, you would think a real life Day After Tomorrow will start from Dec 1st !! We had this BS last year as well. What ended up happening? Brain and Andrew publicly apologising in March of this year, for the forecasts they gave The Met Office may have to face up to the same...by the time March 2006 rolls around The current weather situation seems pretty interesting to me. People will insist on ignoring the present, and wanting to post about the winter to come. The winter we will never forget for a long time apparantly. Which poses another interesting question Does the grass look greener the further into the future we peer? Green grass is what i think a lot of us will be looking at in the months ahead Steve |

In article , writes: If I understand correctly, the Met Office are suggesting that there is a 2 in 3 chance that the coming winter will have temperatures lower than the mean for the past ten years. There is also a 2 in 3 chance that the rainfall will be less than the mean for the past ten years. To be pedantic, I suspect the Met Office is actually comparing the expected figures with the median figures for the past ten years, but that isn't clear in the press release. (Indeed... it could have been more explicitly worded.) In support of Jon's posting, I think the Met Office were referring to the the *long-term" average (ie. a rolling 30-year average) when they talked about "averages" (because those were the figures they produced in the forecast). So, a ~66% chance of being colder than the current 30-year average, but not as cold as 1995/96. For Southern England that would indicate a mean winter temperature of between 3.5 and 4.5 C. For other Regions: Scotland - between 1.8 and 2.7 Northern England - between 2.4 and 3.5 Wales - between 2.8 and 4.2 Northern Ireland - between 3.7 and 4.3 The forecast in http://www.metoffice.gov.uk/research.../headline.html says "The balance of probability is for a winter colder than those experienced since 1995/6.". As far as I can see, it doesn't mention "colder than the mean" or "colder than the 30 year average". What it does do is compare 2 recent winters against the long term average and the winter of 1995/96. I would have thought that there should be no confusion as regards the Met Office forecast. As of the 24th October (when they issued it) they were expecting a fairly high probability that this winter would be the coldest since 1995/96. Whether that turns out to be correct or not we'll have to wait and see. Victor |

I'm 99% sure the original statement was based on 30 years of data. Jon. |

Victor I've since discovered the NAO forecast and statements are based on a 56 year period; the NAO averaging values for the period 48/49 to 03/04. It all makes sense now ;-) Jon. |

In message , Howard Neil writes Will Hand wrote: Well I haven't the foggiest of what a "normal winter" is like up here on Haytor as I have only experienced 3. Impressions so far are of several 1-4cm snowfalls which usually melt by midday. Lots of days with snow falling but not settling. Lots of days with rain and fog. Frost less common than in the southeast, but more days of below freezing wind chill and gales. A bit of sunshine and a good chance of snow on Christmas Day but not a lot before then. If we are to have a "below normal" winter then all I have to say is ooo-er, I'm glad I have good supply of logs :-) So yes, normal can mean different things to different people. I thought a normal winter started off in Autumn with someone telling the press that the following winter was to be severe. This is then followed by ever increasing hype by the press and suitable discussion about the reports in usw. During the actual winter months there are many posts in usw bemoaning the lack of snow (what happened to the forecasts?). When a snow flake lands, usw becomes swamped with weather reports. Then there is spring, when someone tells the press that the following summer will be the hottest since record began. One of the most logical interpretations I have heard for a long time - same old forecasts. Same old mild winter. Cheers Paul -- Sheesh it isn't even November yet and already winter is written off :-( Will. Will, what else can we honestly expect. OK the October blocking by my book was hardly encouraging. A cold wet November is again by the same book our only hope for a winter even down to average. Never mind - my day has gone and I have enjoyed some cracking winters in my youth. I fear for the next generation and the one after. Usual old Hadley Centre stuff - I am not in a position to argue - yet! Cheers Paul -- 'Wisest are they that know they do not know.' Socrates.

It is on all of the GFS forecasts, and presumably will not go away and present us with the forecast 'Easterlies' in due course when the ex hurricanes have blown them selves out in the Atlantic. Phil (in New York awaiting return to London - temp here 54f BKN040 wind from the E this morning) Yes you are right in your initial statement, but it does not follow that a large high over northern Europe will necessarily retrogress. In fact, it can have the effect it is having at the moment, i.e. cause Atlantic depressions to become very slow moving over the UK, and therefore produce mild, wet and windy weather. I would suggest you turn your attention to the development, or not, of an intense high over Greenland. |

Cheers, keith Funny how this has become converted by the press to it is definitely expected that it will be the coldest winter since the big freeze of 1962-1963, (Daily Express) and "may be at least 2 degrees below average" .....is that an oxymoron? Taking the biscuit was the preamble to the radio interview I did last week when the announcer stated he had seen reports that it was to be the coldest winter since the 1800s....... But for any of these extreme stories, although "forecasters" are mentioned, no source or organisation is named. |
