Abstract
The sudden local severe precipitation in Zhumadian City on August 28, 2009 was analyzed from the aspects of meteorological elements change, the atmospheric circulation background, the influence system and the region flow field before and after the severe precipitation. The results showed that this heavy storm had obvious meso-small scale system characteristics, the major affect system were the shear lines in 850 and 700 hPa and the ground convergence line. Through the analysis of the Doppler weather radar basic index such as the reflection factor, the radial velocity and the wind profile, it was find that the characteristics of “V” notched, the hook echo and the eyelone were obvious, those showed that this local heavy precipitation was caused by the supercell storm.关键词
