This paper is based on the simulation of the electrification process of a hail cloud resulting from the interactions (collisions) between hailstones (graupels) with cloud crystals. A thundercloud cell at the maturity stage was simulated. The process of cloud electrification due to the interactions (collisions) of hailstones with cloud crystals is considered. The thermohydrometric structure of the cloud is also taken into account. It is shown that the negative or positive charge acquired by hailstones, is dependent on the effective liquid water content and temperature of the cloud. The cloud charging current was also estimated. It is shown that the thermohydrometric parameters of the cloud determines the resulting polarization of the cloud.
