23 thunderstorms occurred for twenty successive days from July to August, 2000. The weather situation are analyzed. Results show that they comprise 11 local heat thunderstorms and 12 systemic thunderstorms. The characteristic of the two kinds of thunderstorms echo have been analyzed and compared. It shows that there are obvious difference in their echo parameters、spatial and temporal distribution、original source、movement and evolution. The systemic thunderstorm are complex of organizational and systemic multiple cell. The life span of the thunderstorm consist of life span of every cell, so lifetime of them greatly longer than that of anyone convection cell. New cell is created and developed over confluence of cold downdraught and front warm current. The thunderstorms have been developed and maintained by means of this mechanism.
