中文摘要:

      本文对1989和1990两年夏季京津冀地区300km范围内的闪电资料分析了闪电强度,回击数的气候概率分布和闪电日变化及空间分布的气候规律,并将所得结果与美国俄克拉荷马及堪萨斯州的闪电气候特征进行了对比。结果表明,闪电的气候特征可以揭示出特定地区对流活动时空分布的气候规律。

英文摘要:

      Based on the lightning data of 1989 and 1990 summer in Beijing-Tianjin-Hebei district, the climatological probabilities of the strength and stroke number,the diurnal circle and the spatial distribution are given respectively for negative and positve cloud-to-ground lightninig in this paper.The climatological characteristics of the lightning in Beijing-Tianjin-Hebei district are compared with the states of Oklahoma and Kansas,U. S..The results show that the climatological characteristics of lightning could exhibit the climatological regularity of the convective activity.
