Radar studies of intensive hail process developing over the Central part of the North Caucasus 07.06.2012

The results of radar studies of the intensive hail process, which developed over the Central part of the North Caucasus on 07.06.2012, are presented. The analysis includes data on synoptic and thermodynamic conditions of convective cloud formation in the area of radar observations. The problems of radar structure and dynamics of development of separate hail cells and large-scale convective clusters are considered in detail. For the most intense hail cells, the parameters of the microstructure were calculated using the two-wave radar method. The results of the comparison of the maximum hail size by ground and radar data show their good compliance. Analyzed the time course of basic radar parameters hail cloud, the reconstructed trajectories move radioecho individual hail cells.
