Thunderstorm Activity Forecasting Based on the Model of Cumulonimbus Cloud Electrification

I. M. Gubenko and K. G. Rubinshtein

The physical and mathematical description of the model of cumulonimbus cloud electrifi- cation is presented. The model uses the forecasts of the WRF-ARW numerical mesoscale model as inputs and allows predicting the parameters of the atmospheric electric field including those typical of thunderstorm activity. The prognostic values of electric breakdown are compared with the observed thunderstorms.
