摘要：

利用甘肃中部地区和浙江地区的闪电定位资料，研究了闪电活动的时间和空间分布特征；并结合地面和探空资料，分析了兰州和杭州附近地区在有闪电活动时闪频数与大气不稳定参数的关系。结果表明，2地区的地面相对湿度、沙氏指数、对流有效位能和对流抑制能量与其地闪频数具有较好的相关性，杭州地区地闪频数与对流抑制能量的相关性较大，而兰州地区地面相对湿度对闪电活动的影响更为明显。

Abstract:

Based on the cloud-to-ground flashes data obtained by lightning location system from Gansu and Zhejiang, the temporal and spatial distrbution features of lightning activities have been analyzed respectively. In addition, by using ground and sounding data in lightning activity processes, the ralationship between lightning activity and atmospheric instability parameters is analyzed in the paper. The results indicated that the relative humidity of surface, SI, convective available potential energy(CAPE) and convective inhibition energy(CIN) were all impact factors of lightning activities, but the CIN has a greater impact on the lightning activities in Hangzhou and the relative humidity of the surface play a decisive role in Lanzhou.
