| 摘 要： | 利用NCEP(分辨率2.5×2.5)再分析格点资料和北京"9210"系统下发MICAPS格式常规资料对影响广西6次暴雨过程中的影响天气系统分型,在此基础上利用T 213物理量(比湿、水汽通量、水汽通量散度、垂直速度、涡度、散度、假相当位温500hPa与850hPa的差值、K指数)格点资料对这6次过程进行垂直剖面和前后时序分析,试图找出不同类型天气系统影响广西造成暴雨过程的一些物理量的共同特征。

| Abstract: | Using the NCEP reanalysis grid data and the general data of MICAPS format given by the "9210" system of Beijing,we dispart the weather systems of 6 times rainstorm processes that influence Guangxi,and using the physical data(specific humidity,moisture flux,moisture flux divergency,vertical vorticity,vorticity,divegency,difference of potential pseudo-equivalent temperature between 500hPa and 850hPa layer,K index) of T213,we analyze the vertical section and time sequence of the 6 times processes to find out the common characteristic of several rainstorm processes that influence Guangxi caused by different weather systems. |
