    UK Airmasses

    The main Air Masses that affect the United Kingdom Air Masses are defined as a large body of air (covering many thousands of square kilometers) which at any given level has almost uniform temperatures, lapse rates(see topic on this), and humidity. Their Source Regions are large areas of the earth where air often stagnates for long periods. Examples of these are the Polar Regions, and the sub tropics. Air over any of these regions may stay for long periods and thus picks up the characte

Southern areas see the warmest and sunniest weather as they are closest to the influence of ridges from the Azores High. Low pressure dominated scenarios

    The Arctic Oscillation Arctic Oscillation is an important lead on expected winter conditions in the Northern Hemisphere, loosely described as negative ( colder ) positive ( milder).  The image below gives you a great contrast of a winter we will all easily recall with an extremely negative AO and a little further back a winter at the opposite end of the scale.   When considering the overall forecast for Winter it is important to note any variables which provide clues as to which
