Analysis on Impact of Terrain on Extremely Rainstorm in Southern Shanxi under the Background of Block High
一次阻高背景下地形对晋南特大暴雨的作用分析

Take a rainstorm occurred in Yuanqu county,Shanxi from 29 to 30 July 2007 as a case,based on the observed data,automatic meteorological data,and GMS infrared satellite image,the development characteristics of terrain vertical velocity,shear vortex,divergence,and energy were analyzed.The 500 hPa heights and temperature before rainstorm were combined and analyzed,combining experimental results by numerical model,all shows that:(1) The forming and long-term maintaining of block high and cutting low at 500 hPa ...
