摘要: Classifications of atmospheric circulation patterns are useful tools to improve the description climate a given region and analysis meteorological situations. In particular, weather pattern (WP) classifications could be used spatial heavy rainfall. Here, bottom-up approach, previously build WP classification in France, is applied for definition Austrian The optimal extent position geopotential fields taken into account studied. proposed shown coherent with general knowledge on synoptic situations responsible rainfall over Austria. Moreover, has good performances terms compared 152 COST 733 defined same region. we show that choice fields, their characteristics relevant capturing physical information it can performances.
