Numerical Simulation and Dynamic Analysis of Mesoscale Torrential Rain Systems
暴雨中尺度系统数值模拟与动力诊断研究

Some progresses in numerical simulation and dynamic analysis of mesoscale torrential rain systems in recent years are summarized in this article,which are divided into several sections,such as generalized moist potential vorticity,Meiyu front and its frontogenesis,instability of mesoscale rainstorms,window partition in a limited region and its application in the identification of mesoscale rainstorms,mesoscale wave-flow interaction,and numerical simulations.It shows that assimilation of radar observations into numerical models improve the simulations well and some new diagnostic tools such as non-uniformly saturated moist potential vorticity,convective vorticity vector,deformation,and window partition in a limited region are widely used in diagnostic analysis of mesoscale rainstorms and tropical convections.And wave-flow interaction theory is also extended to be used in the dynamic analysis of mesoscale torrential rain systems.
