台风“榴莲”暴雨的湿位涡诊断分析

Diagnostic analysis of location vorticity of humidity in typhoon "civet durian" storm

分析 2 0 0 1年 7月 2 - 3日台风“榴莲”暴雨过程中湿位涡及其各分量的变化 ,发现对流层低层 85 0 h Pa湿位涡的负值中心、 70 0 h Pa湿位涡的正值区与强降水中心相对应 ;急流与层结稳定度的变化 。

The analysis of location vorticity of humidity in typhoon 'civet durian' storm process during July 2 ~ 3, 2001 and the variation of each components found that the negative value center of lower 850hpa location vorticity of humidity and the positive value area of 750hpa location vorticity of humidity in troposphere correspond to the heavy precipitation center. Changing of jet stream and stratification stability has an effect on the changing of location vorticity of humidity.
