Atmospheric electric field strength and thunderstorms in the North Caucasus

Аннотация

The results ofthe joint analysis ofthe data ofinstrumental observations using LS8000 lightning detector, weather radars (MRL-5 and DMRL-C), and electric field strength sensors as well as the results of numerical simulation of electric parameters of developed convective clouds based on the three-dimensional model worked out at High-mountain Geophysical Institute are presented. Some results of mathematical modeling of electric charges and fields in a convective cloud in the process of its evolution are described. The computations are based on the real data of atmospheric upper-air sounding on the days with thunderstorm and hailstorm processes in the North Caucasus. The effects of electric processes on the formation of micro structural parameters of convective clouds and precipitation are studied.
