Annotation The article is based on a mathematical model showing the evolution process for a particular case of a convective cloud. In this article, not only spatial, but also thermodynamic parameters with the inclusion of microstructural ones are investigated. The use of the model implied its unsteady numerical character. Significant amounts of microphysical and electrical processes in convective-type clouds have been studied very little. This is due to their complexity and inaccessibility for experimental research. The analysis has shown that the interaction of physical processes in the clouds, which undoubtedly plays an important role in the formation of microstructural characteristics, has not been studied enough. Due to the unavailability of instrumental studies of powerful convective and especially thunderstorm clouds, mathematical modeling has become the main method that allows a detailed analysis of the formation of their various parameters and interaction of processes. According to the results of the work, a mathematical model of a three-dimensional view was compiled, which characterizes the possibility of using cloud prediction processes based on micro-world processes. A mathematical model was investigated and presented with changes in the horizontal wind field within the atmosphere. In particular, the characteristics of the formation and development of clouds are distributed. The main results of numerical experiments can be called the fact that a change in the direction and speed of the wind in the atmosphere contributes to a direct effect on the formation of clouds. It is more clearly shown that the impact is carried out within the framework of the study of the formation of areas of size, the localization of individual sites for collecting drops, as well as the forms and methods of forming ice crystals. The possibility of precipitation formation depending on the phenomenon being studied is also determined
