摘要：

We present the data on the dynamics of the electric field strength and volume charge of two severe thunderstorms in different regions of the world, namely, in the North Caucasus (Russia) and in Beijing (China). The data were obtained as a result of modeling, using a numerical three-dimensional non-stationary model of convective clouds developed at the A. I. Voeikov Main GeophysicalObservatory. The modeling was based on rawinsonde data obtained during the modeled thunderstorm events. The spatial distribution of the electric field strength and space charge inside the cloud and in its vicinity was calculated. The multilayer charge structure of the cloud with thin layers of "shielding" charges is reproduced and the corresponding structure of the electric field strength is presented for each electrification stage. The dynamics features of the electrical structure of the studied cumulonimbus clouds are discussed. The case of modeling of a cloud with inverted polarity is considered. Verification of the numerical model based on empirical models of convective cloud electrification showed a satisfactory result.
