    To be honest, I think it's been warm in the last 20 years, but warming hasn't really happened. If you look at the graph and there really hasn't been any warming for about a couple of decades, just warm years on a level trend. http://www.metoffice.gov.uk/hadobs/hadcet/graphs/HadCET_graph_ylybars_uptodate.gif

    I think 2011 was the 11th warmest year globally. When we and much of America experienced the mild weather last winter, parts of Canada and Alaska were experiencing some of their heaviest snowfalls ever. When the jet stream does one thing somewhere, the opposite nearly always occurs somewhere else!

    I get bored with how numerously he says "at times".😞

    I'm also one for really heavy rainfalls, I find them really exciting. I don't see why people get so depressed by it, yes, I agree, you can't do much, but living in this country I have just learn't to get use to it, and actually enjoy it. I would also love to live through he biggest negative temperature anomaly for a Summer month, it would just be amazing to experience and to has memories of how strange that month was.

    The April northerlies and the May easterlies would have been brilliant during winter.

    What on Earth is going on with Hadley?!

    Love temperatures in the day maxing out at 24C and occasionally higher. The odd 30C does make it all the more exciting, with thunderstorms to follow. I'd like temperatures in the night to actually drop to single figures just so you can start the day on a fresh note.

    Totally agree, could still happen though (just).

    It looks like Corbyn's prediction won't come off now, although it was fairly accurate for the first 20 days, not quite as cold as he said though. We still experienced the northerlies and the snow that he mentioned.

    That is very interesting, certainly not something I picked up on. Let's see if Summer and Winter pan out similarly. Just to add, looking back another 117 years we don't see this Spring warmth. It's a shame we don't have records going back a few years further to see if the Spring warmth was a theme in years just prior to 1659. However, as you mentioned, looking a year on from each of those years and we see that April 1777 also came in at 7.2C on the CET, as did this year, and May 1894 came in at 9.2C, which is similar to the current CET, although this years will probably finish higher.

    Thanks. It's interesting to see that the two warmest were actually in less recent times.

    Do you have any stats on the coldest ever 16th April to 15th May period?
  13. Relativistic
    Sorry about the mistake.

    Hi, I don't post on here much but I just want to clear up something. I think a few people are a bit mislead by the forecast. The Express did the usual and overhyped it and I think a few people were caught up in that. The forecast states an 80% chance for the coldest in 100 years and a 90% chance for this May coming in in the top 5 coldest in 100 years. I don't think anyone should be dismissing the forecast just yet, as it could come in the top 5 coldest quite easily if things remain cool. (I'm not specifying you Jackone, it's just this quote has the forecast in it).

    I'll go for 9.9C please.
  16. Relativistic
    Okay, thanks. About the EP Flux, at 10hPa it is and has been in a poleward direction, yet the warming at 10hPa hasn't really propagated downwards. Am I wrong in saying that this is what should happen or is there a reason for this?
  17. Relativistic
    Has anyone got any links that they can give me for zonal wind forecasts? Thanks.

    Is this also similar to January 1987? Forgive me if I've done this wrong, I'm still getting use to some of these charts. Edit: Just realised that this is displaced over Greenland as well.

    I'm going for a January starting off slightly mild and quite windy with a few Atlantic depressions driving through the UK, followed by a colder 2nd half. Then I think February will be really cold, with a CET of about 1C.
  20. Relativistic
    I'm going for a warmer first half of January and a colder second half, and a final CET of 3.4C
  21. Relativistic
    Thanks, it's good to know I'm getting somewhere!

    I have read through some recent pages to get a bit more of an idea on the subject and I have made out the following: 1. Rossby waves can travel to the vortex and either penetrate it underneath from the troposphere or over the top of the stratospheric vortex, introducing warmth and causing disruption. 2. Rossby waves can be seen on 500hPa SLP charts as troughs. 3. High snowcover in the NH allows for the suns radiation to be reflected back up into the strat, introducing warmth. 4. Mountain torques are events where the air pressures either side of a mountain range are different, what this means though, I do not know. The only question I have is; how are MT's and Rossby waves linked? Any answers would be much appreciated.

    Thank you! I will read through the thread and have a look. Sorry about the location thing, I've set it now.

    Hello all, I'm new to this forum but read it every now and then. It's very interesting and there are some very knowledgable people on here. I have a few questions to ask firstly though. I know a bit about SSW's, what effects they have, but would anyone be able to tell me what factors help to cause an SSW's. I've done some research and am I right in saying that the stronger the BDC, the better as more ozone gets into the strat and more of the suns radiation can be absorbed, causing it to heat up? Am I also right in saying that for an SSW we want a -QBO at low solar flux and a +QBO at high solar flux? I know that in increase in mountain torque events can lead to strat warming (?), but how exactly? Also, what is mean't by waves and how do they effect the strat? If anyone could answer my questions I would really appreciate it, and if anyone wants to throw in any more info that would be awesome. This is a subject I find fascinating and I really want to learn more about. Thanks.
