Features of Lightning Data and Radar Echo of a Heavy Torrential Rain in Hebei Province

The characteristic of lightning data and radar echo of the heavy torrential rain happened in southwest of Hebei during August 3—5 in 1996 was analyzed by the lighting data,713 radar echo and nonconventional observational data every hour.The results show that the rainfall process is a mixed rainfall,and the number of cloudtoground lightning,lightning intensity,and the intensity of radar echo have a instructive meaning on rainfall intensity,rainfall distribution and the development of the mesoscale convective system.
