Abstract:
In the present study, RADAR products (Reflectivity, Echo Tops) of Doppler Meteorological Radar for Weather Surveillance (WSR), in C band, of National Meteorological Administration were used to characterize four precipitation events that took place in Bucharest metropolitan area during 2019-2021. The type of precipitation and its intensity were identified from the reflectivity data and from the Echo Tops product - the maximum height associated with the onset of the precipitation events. The study cases are as follow: a long-lasting moderate rain, a heavy rain and two case studies for long-lasting extreme rain/ hail above the Bucharest area (44 ° 26 'N, 26 ° 06' E). Three events took place during the convective season and one in end of February 2021. Dynamics of each event was pursued by combining RADAR outputs with synoptic weather charts and lifted index and convective available potential energy parameters for detecting the onset of convection.
