Popis: Results of regional climate modeling PRECIS with high spatial resolution (25 km) were used to investigate mesoscale features of atmospheric circulation in the Black Sea Region for 30-yr period. Method based on Ocubo-Weiss criterion was used to detect and track subsynoptic eddies. Several types of cyclonic eddy were discovered and studied: winter Caucasian coastal, summer Caucasian off-shore, ambient cyclonic eddies, and rare quasitropical cyclones. For Caucasian eddies statistics of their life-time and intensity, as well as histograms of diurnal and seasonal cycles, are presented.
