Trends in frequency and persistence of atmospheric circulation types in COST733 classifications over Europe derived from a multitude of classifications

Popis výsledku v původním jazyce

The aim of this study is to quantify changes of atmospheric circulation over Europe using a large number of classifications of circulation types that were collected and developed within the COST733 Action &apos;Harmonisation and Applications of Weather Types Classifications for European Regions&apos;. Circulation changes over Europe are studied in terms of changing seasonal frequency and persistence of daily circulation types in the period September 1957-August 2002. The extensive collection of both subjective and objective (computer-assisted) catalogues of circulation types in 12 European domains serves as a platform for comparison of different classification methods, varying numbers of circulation types, sequencing of input sea-level pressure data, and spatial scale of circulation processes. The overall picture of frequency and persistence trends is consistent with two large-scale tendencies: strengthening and eastward shift of the North Atlantic Oscillation, and a northwestward shift of storm tracks. There is, however, a limited consistency in the trends between individual classifications. This inconsistency leads us to the recommendation that results of climatological analyses based on a single classification should not be generalized and overinterpreted; it is highly advisable to simultaneously use multiple, and as many as possible, classifications in climatological studies.
