A quite fascinating thread and congratulations to those involved in it,a lot of that to be frank goes way over my mortal head! My opinion,fwiw,is that GW has made a *massive*difference to our winters in particular.The domainance of the AZH and Icelandic low has been truely horrific for the cold lovers in this country during the winter months.Have to say i am firmly in the sceptics camp wrt LRF's,I dont believe in them at all.Gegraphically speaking the UK is not in a good spot for sustained cold,obviously we have the Atlantic to thank for that,one thing that does stand out for me personally is the lack of cold or polar NW'lys during the post 1988 era,anybody have any theories as to why these synoptics rsrely rear their wonderful head nowadays?
