Abstract

The work is devoted to investigate the aerosols influence on the parameters of thunderclouds. Numerical simulations of thunderstorms in Nizhny Novgorod region using the WRF-ARW model with parameterizations of microphysics with and without aerosols were compared. Also the modeling radar reflectivity was compared with the radar data. In line with the simulations of the change in CAPE the following features were detected: when aerosols are taken into account, the area occupied by a convective event increases, and the peak of convective activity shifts in time. Thus, consideration of aerosols in mesoscale modeling of atmospheric dynamics and electrification processes is important.
