摘要
利用MICAPS系统提供的大量天气实况和降雨实况,对云南省文山州2007年初夏第一场透雨的主要影响系统、水汽条件及动力条件进行分析,并对本次过程的雷达回波资料作简单的定量分析。发现云南文山一直处于副高外围的西南气流中,中低层切变南压过程中,一直维持在孟加拉湾一带的孟湾风暴沿着副高外围源源不断地输送水汽,这两者的密切配合,是这次持续强降水天气产生的主要因素。雷达回波图上也直观地显示了系统的移动路径及移动过程。
By using a great amount of weather and rainfall facts provided by MICAPS system,the moisture condition,dynamic condition and the main system were analyzed,which affects the first soaking rain in early summer of 2007 in Wenshan,Yunnan,meanwhile it makes a simple quantitative analysis on the radar echo information of this process.It is found that Wenshan has been on the periphery of subtropical high southwest air current.In the course of moving south of the medium and low pressure shear,the storm which has be...
