Numerical simulation of electrical processes in storm clouds
The paper presents a deseription of the ealeulation of eleetrieal parameters in the developed three-dimensional non-stationary mathematieal model of the eonveetive eloud with detailed aeeount of thermodynamie, mierophysieal and eleetrieal proeesses. Some results of ealeulations of the eleetrie field potential and intensity in the storm eloud at different stages of development are presented. Hydrothermodynamie bloek model eonsists of the equations of motion that deseribe moist eonveetion in the Boussinesq approximation, mierophysieal unit based on the use of kinetie equations for the distribution funetions of partiele mass deseribes the proeesses: nueleation, eondensation, eoagulation of the droplets with the droplets, sublimation, aeeretion, freezing droplets and the interaetion of eloud partieles under the influenee of the eleetrie field of the eloud.
