3D Modeling on Relationships among Intracloud Lightning,Updraft and Liquid Water Content in a Severe Thunderstorm Case
强雷暴个例云内闪电与上升气流及液水含量关系的三维数值模拟

A three-dimensional hail-bin cloud model coupled with electrification process has been developed and used for simulating lightning process in a severe thunderstorm in Beijing City in China. The characteristics of intracloud lightning channel and its relationship with updraft and liquid water content have been analyzed. Results indicate that in the evolution of the thunderstorm, snow particles are often formed where updraft is weaker and liquid water content (LWC) is lower. Snow particles develop there, and ...
