ABSTRACT. – The meteorological radar, due to its temporal and spatial resolution, has become an indispensable and necessary tool in the meteorologist's hand in order to create a climatology of the meteorological phenomena, to identify synoptic-orographic mechanisms that lead to their appearance and timely issue of weather alerts. This is observed from the analysis of June between 2004 and 2019 with the help of the WSR-98D radar from Bobohalma near Tȃrnǎveni. Using certain radar parameters: reflectivity, hail size, the number of identified storms, the years were ranked according to their atmospheric instability, in order to compare them with climatological data. Thus it was obtained that in the years 2018, 2016 and 2019 the atmospheric instability the highest of, obtaining a good correlation with the average deviations of the geopotential at 500 mb and of the isotherms at 300 mb and 850 mb or with the low values of the LI index (instability index).
