Based on the weather radar data of Chongqing Municipality from 1982 to 2003, a statistical analysis of the climatic characteristics of the radar echoes of the various types of the meso-scale severe convective weather, such as heavy rainfall, hail, thunderstorm. It shows that (1) the spatial-temporal distribution of the echoes of the events is uneven. (2) The vortex echo is the primary characteristic of the heavy rainfall events, which may be related to the terrain of the Sichuan Basin and the southwest vortex. (3) The hail echo is the main agglomeration. (4) The thunderstorm echo is characterized as striation and bow-shaped.
