THE PRESENT-DAY CLIMATE OF EASTERN EUROPE AS VIEWED IN THE CONTEXT OF ATMOSPHERIC CIRCULATION CHANGE
Keywordswarming, atmospheric circulation, etalon MSLP field, synoptic pattern, extreme weather
AbstractClimate change over the territory of the Atlantic-European sector during the recent decades is studied with reference to changes in the large-scale atmospheric circulation. The classification of synoptic patterns (from the class of most probably to the class of least probable fields) is given for winter and summer for the last three decades, starting from 1974-1983. The synoptic pattern of the most probable class of field sea-level pressure shows high pressure over Europe in 1974-2005, which from decade to decade occupies more and more territory in summer and winter. The high temporal stability of predominant synoptic patterns is responsible for long-lived events of extreme warm and dry weather in winter and in summer for heat waves and droughts. The synoptic patterns corresponding to such dangerous weather conditions as extreme cold, strong precipitation, glaze ice, strong winds, hail etc. are discussed as well.
