Răzvan Alexandru SOMESAN, Grigore MAKKAI
ABSTRACT: This paper presents an analysis of synoptic and mesoscale phenomena that led to the severe weather in Mures County (Romania) on 24th-25th May 2015, as well as the registration of large hail in the locality of Band. For the synoptic analysis ECMWF numerical model outputs were used, ALARO, COSMO limited area models, visible and infrared satellite images, maps and weather reports used in forecasting and in meteorological diagnosis, radar data imaging and data processing, provided by the Doppler WSR – 98D radar in Bobohalma, the Skew-T charts in Târgu Mures, data from Targu Mures weather station, data from the pluviometry stations, signs of instability. Through these sources and procedures a multicellular type mesoscale convective system was identified on May 24th 2015. The areas where hail was reported were located within the county, but also in its vicinity, and the route of its movement was examined, as well as its size on consecutive the radar scans.
