摘　　要：利用卫星云图、雷达资料和闪电信息对 1998年 7月 2 3日和 8月 16日夜间发生于北京地区的两次雷击事例进行了分析。结果表明 ,这两次雷暴过程是因局地对流云的发展所致 ,雷暴中的电活动与对流活动密切相关 ,闪电资料可以及时发现强对流的活动及其变化趋势 。By using the satellite cloud pictures,Doppler radar and lightning information, two cases of lightning strokes were analysed in Beijing area during the summer of 1998. The result shows that local convection cloud growing cause strong storm activity. There are closer relations between electrification and convection process of thunderstorms. The lightning data is a useful tool in short range forecast. It can monitor development and evolution of convective system.
