ABSTRACTThere are several cyclone genesis regions in the Mediterranean basin with climate impacts on the Balkan Peninsula including territory of Serbia. In this study, we used sea level pressure and geopotential high of 500 hPa and principal component analysis to identify atmospheric circulation types for Southeast Europe domain, especially those with cyclonic activity on the ground and in the middle of the troposphere. The precipitation distribution was studied depending of cyclone position and air flow using daily values for 30 stations in Serbia. For this purpose, we used geostatistical interpolation method, regression kriging with additional predictors such as digital elevation model, latitude, and longitude. The high resolution spatial model showed regional differences in daily precipitation depending on whether cyclone genesis is in the Ligurian and Adriatic basins or eastern Mediterranean, but is some cases deep cyclone over Balkan can cause extremely high precipitation sums. The extreme precipitation events (over 90th, 95th, and 99th percentile of the empirical distribution of daily precipitation intensity) were analyzed separately.
