Future changes vary a lot between different models, such that the pdf looks silly. Cheers Phil At 11:37 14/04/2008, you wrote: Hi Phil, I have decided to go to the UKCIP meeting on April 22 so will try and lobby for all WG variables and hourly to be retained. What's their problem with wind speed? They do have a habit though of not listening to us stakeholders and ploughing on regardless (unless one is the Environment Agency of course - you didn't' read that last bit!) Thanks for the paper - I will have a look. I think negative daytime UHIs are a feature of most cities - but I'll see if I can track down a reference to back this statement up! It is indeed unfortunate that LWC is up at the top of the building - do you think we should try and apply a correction?

Colin is writing up his bit. You ought to go to the UKCIP08 SG meeting on April 22 if you can. There is a move to try and drop wind speed from the WG variables. Also a lesser move to drop hourly. I'll not be there - in Geneva. I'd like both to stay if at all poss. So need a few to talk up the need. I didn't tell you the last few sentences. I though the attached might be interesting. It shows little more urban related trend in NY over the 20th century. Also on warmest days it is warmer outside the city. This is probably unique to NY. The reason LWC isn't as warm as LHR on the very warmest days is because the measurements are 50m up on a building!
