摘　　要：统计了江苏省气象部门雷电探测系统2008—2009年闪电记录,对江苏省闪电强度、闪电频数等闪电特征进行分析,得出江苏省的雷电流强度和闪电分布都有明显的时空差异,并且闪电频数和强度在空间分布上基本呈相反分布;同时利用地闪记录与雷暴日数的关系,得出了适用于江苏13个地级市的地闪密度计算公式.Through analyzing the lightning data from 2008 to 2009 detected by lightning detection system of Jiangsu provincial meteorological department,the features of lightning intensity and frequency are studied in this paper. Resuits show that they both have obvious temporal and spatial differences, but the spatial distribution of the lightning intensity is opposite that of the lightning frequency. According to the relationship between lightning and thunderstorm days,equations for calculating density of ground lightning in 13 cities of Jiangsu are given.

关 键 词：闪电强度 闪电频数 雷暴日 地闪 密度
