The paper considers the characteristics of cloud convection obtained in the course of computational experiments on the basis of a three-dimensional physical and mathematical model of convective clouds, which takes into account in detail the microphysical processes of nucleation, condensation or sublimation of water vapor, coagulation and accretion of precipitation particles, accumulation of volume electric charges, and an increase in the electric field strength. clouds due to charge separation processes occurring during the rapid freezing of large supercooled drops, accretionary growth of cereals and hailstones. Based on the data of numerical modeling using the noted model, the location in the volume of the microstructural parameters of thunderstorm clouds (water content and ice content), space charges, electric field strength, radar reflectivity in the centimeter range, and other parameters at fixed times of cloud evolution was investigated.
