Abstract:Rainstorm processes in Hubei Province from years 2007 to 2008 are selected to study the characteristics of the radar echoes. First， thirty two regional rainstorm processes are determined according to the rainfall data analysis. Then, by analyzing the Doppler radar reflectivity echo shapes, structures and so on, the four kinds of regional rainstorm radar echo models in Hubei Province are induced. Moreover, the rainstorm region and the major impact system’s synoptic characteristics of each kind of rainstorm echo are comparatively analyzed. The results show that, the four kinds of regional rainstorm radar echo models are the comma shaped, the whirl shaped, the complex vortex belt shaped and the band shaped, and they are closely related to the meso α scale cyclone wave disturbance on the front surface, the development of the low vortex systems in eastern Sichuan Province, the combination of the Meiyu front and the low vortex system, and the formation of quasi stationary front shear line on the cyclone waves， etc.
