Abstract

A new approach for taking into account the impact of turbulence on thunderstorm electrification using the numerical model WRF-ARW is presented. For this, a method for calculating the turbulent energy dissipation rate on the basis of the radar reflectivity distribution and characteristic values of the turbulent energy dissipation rate in various types of clouds is developed. The charging current is corrected by the value of the turbulent current component determined for the obtained turbulent energy dissipation rate. Thus, calculation of the electric parameters (electric potential and electric field) of thunderclouds is carried out taking into account the influence of turbulent mixing on thunderstorm electrification.
