摘要
通过对西昌发射场及川西南地区 1 994年至 1 998年的交汇云地闪探测资料进行详细分析 ,得出了该地区闪电强度和回击数的气候概率分布 ,闪电的日变化、年变化和空间分布的气候规律 ,并将所得结果与我国京津冀地区的闪电气候特征进行了对比分析。结果表明 ,闪电的气候特征可以揭示特定地区对流活动时空分布的气候规律。
During 1994 to 1998 the lightning sounding data of Xichang launching site and southwest of Sichuan district are analyzed in detail. The climatological probabilities of strength and stroke number are given respectively for cloud to ground lightning. The climatological laws of the diurnal circle and yearly variation and the special distribution are also given respectively for lightning in this paper. The climatological characteristics of the lightning in Xichang launching site and southwest of Sichuan district are compared with Beijing Tianjin Hebi district. The results show that the climatological characteristics of lightning could exhibit the climatological regularity of the connective activity on time space distribution.
