  1. Another one I had been wondering about:

    GIN SEA= Greenland Iceland Corridor where cyclonic genesis occurs. With Atlantic highs keeping the sytems tracking west to east roughly to the north of the UK bringing mild wet stormy weather to the UK.

  2. Good to see that others find this thread useful too. Couple more to add to the collection. Taken from another thread where I was wondering what some abbreviations meant....

    From Steve M:

    PVA stands for positive vorticity advection- when occuring from the subtropical side of the jet stream will potentially allow deeper cyclogenesis across a region because of the raised thermal gradient-

    PFJ Polar front jet stream- The jet stream that is the marked boundry between the cold dry air masses from the North and the mild moist ones from the south-

    PPN on the northern side is normally in the form of convectice showers where as on the southern side you are more likly to have rain belts from layered clouds....

    AO - Arctic Oscillation - We need a definition for this, any offers?

    I would also like to suggest that the first entry on this thread is maintained as a repository for abbreviations. While we do now have this thread, I still urge the more knowledgeable members to use abbreviations rarely in their posts or to at least give the full term once in the text. It will just make post more usable for the majority. OK whinge over. :D:)
