摘要
Abstract
[Objective] The research aimed to study the establishment of a kind of three-dimensional thunderstorm cloud electrification-discharge model. [Method] Based on a kind of three-dimensional strong convective cloud model, several parameterization schemes of electrification-discharge mechanism which were mature and had experimental basis were coupled into the strong convective cloud model. The three-dimensional strong convective model could simulate electrification-discharge process, and the three-dimensional thunderstorm cloud electrification-discharge model was established. [ Result ] By numerical simulation method, a kind of three-dimensional thunderstorm cloud electrification-discharge model was established. The model not only could assess the relative importance of various kinds of electrification mechanisms under different environments, but also described formation of charge center and electrical field in the thunderstorm cloud, occurrence position and propagation process of lightning, its influence on charge distribution. The most important thing was that it could quantitatively describe the relative relationship between power, microphysics and electric process in the evolution process of thunderstorm cloud. [Conclusion] The research provided powerful foundation for further studying the lightning characteristics of different thunderstorm clouds, the relationship between lightning characteristics and power, microphysical process, and deeply discussing the early-warning forecasting technology of thunder and lightning activity.关键词
