Analysis of precipitation quantities and trends from Pannonian and Peripannonian parts of Serbia

Annual and seasonal quantities and trends of precipitation were analyzed for twelve stations located in Pannonian and Peripannonian parts of Serbia. Investigated period was from 1949 to 2010. The results showed that the precipitation trends during winter and spring had decreased, while in summer and autumn had increased. Tendencies of annual precipitation time series show rise on most analyzed stations as a consequence of rainy years and extreme rainfall events in the last 15 years. In the investigated period, 10 years with severe and extremely severe drought occurred and they tend to occur in subsequent years. Cluster analysis gave very good picture of precipitation distribution. Analizirali smo letne in sezonske količine ter trende za 12 meteoroloških postaj v panonskemin obpanonskem delu Srbije za obdobje 1949-2010. Rezultati kažejo trend zmanjševanja padavin pozimi in spomladi ter trend porasta poleti in jeseni. Časovne serije letnih količin padavin kažejo porast padavin na večini preučevanih postaj in so posledica bolj namočenih let ter ekstremnih padavinskih dogodkov v zadnjih 15 letih. V preučevanem obdobju je bilo tudi 10 let z močno in ekstremno sušo s tendenco pojavljanja v več zaporednih letih. Dobro sliko o razporeditvi padavin je dala tudi metoda razvrščanjav skupine (cluster analiza).
