The paper presents a three-dimensional numerical model of a convective cloud taking into account electrical processes. A specific feature of this model is the use of detailed microphysical equations with several dozen classes of drops and crystals (explicit microphysics). In particular, the model takes into account 61 categories of droplet sizes and 75 categories of crystal sizes. With this model, we investigated new important aspects of the electric charge mechanism and field formation in clouds, we also noted the interaction of thermodynamic, microphysical, and electrical processes. The spatial distribution and quantitative values of volume electric charges and field strength in and around the cloud at successive time points in the evolution process are determined. The model was used  to quantify the influence of electrical processes on precipitation formation.
