| Abstract: | By using NCEP 6-hourly reanalysis data、3-hourly TRMM data、the hourly satellite TBB data、HYSPLIT v4.8 Model,the rainstorm event over Guangzhou during 6-7 May 2010 is analyzed.Results show that:rainstorm is appearing ahead of 500hPa ridge.Surface shear、lower-vortex,front are favorable to the development of the rain-storm system.The stagnation of MCC in Guangzhou which generated in the northeast of Guangxi is the direct reason for severe heavy rainfall.The pumping action of upper-level divergence may be a trigger mechanism of this heavy rain.South China Sea is the main source of low-level water vapor.High-level airflow affects Guangzhou from west.Convergence and divergence of water vapor have an indicative meaning for development of rainstorm. |

| Keywords: | ahead of High-altitude ridge the pumping action of upper-level rainstorm MCC |
