NUMERICAL STUDY OF MICROSTRUCTURE AND ELECTRICAL CHARACTERISTICS OF CONVECTIVE CLOUDS
A three-dimensional nonstationary numerical model of a convective cloud with detailed account of thermohydrodynamic, microphysical and electrical processes is developed. The process of accumulation of electric charge during freezing of drops and accretion is formalized. The model allows calculating thermodynamic, microstructure and electrical parameters of convective clouds at different stages of cloud development. Some results of calculations of the electric field potential and intensity in the storm cloud at different stages of development are presented. Quantitative characteristics of volume charge, potential, electrostatic field intensity at different stages of cloud development are determined.
