Diagnostic Analysis and Numerical Simulation of a Torrential Rainstorm Process Caused Southwestern Low Vortex
一次西南低涡暴雨过程的诊断分析与数值模拟

A case of torrential rainstorm process caused by a southwest vortex(SWV) is diagnosed using the observation data,FY-2C satellite image,and NCEP/NCAR reanalysis data.The result shows that the main influencing systems are South Asia High,lee trough,and shear line from the tropopause to near surface in vertical direction.The tropical storm '0907'(Goni) is another key factor in this case.The torrential rainstorm is directly caused by three mesoscale convective cloud clusters continuously,which occurred asymmetr...
