摘要：

Characteristics of cloud-to-ground (CG) lightning flashes in Pingliang have been analyzed by using the data obtained from a broadband slow antenna system with a time resolution of 1 MHz from June to August, 2001. It has been found that lightning discharges in plateau summer thunderstorms usually present some special characteristics compared with American summer thunderstorms and Japanese winter thunderstorms. On the average, the zero crossing time of the first stroke radiation fields is 63 μs and 66 μs for positive and negative CG flashes, respectively. The overshoot depth is 20% and 31%, respectively. The initial peak of the return stroke radiation field is followed by several subsidiary peaks. The time interval between the successive peaks increases whereas their amplitudes decrease by order.
