SYNOPTIC CONDITIONS ASSOCIATED WITH EXTREME WEATHER EVENTS IN THE WESTERN PART OF THE BLACK SEA. A COMPARATIVE STUDY

Abstract

The genesis conditions and evolution of two violent storm events are investigated in this paper. They were determined by the same pattern induced by the interaction between a high pressure system dominating Europe and a Mediterranean low pressure field with travelling disturbances moving to the Black Sea. The purpose is to understand what regulates the differences between the duration and intensity of these storms. For their comparison, the NCEP-500/850 and SLP analyses, ALARO model outputs, atmospheric soundings and temporal variations of meteorological parameters recorded by the weather stations have been used. The differences between the two storms consist in the dynamics of the cyclones at sea level and in the upper atmosphere.
