| 摘 要： | 利用高频次多普勒雷达回波资料、闪电定位仪及区域自动站资料，对2011年6月9日湖北暴雨过程的闪电特征进行分析。结果表明：MCS不同生命阶段地闪所处位置不同，正、负闪同时跃增到峰值是MCS成熟阶段的标志之一，地闪密集区和MCS中移速较快的强回波位置基本吻合，MCS强回波区域出现正、负闪和45-55 dBz回波后部区域对应较好，强降水发生在MCS成熟后趋于消亡阶段。

| Abstract: | Based on the Doppler weather radar echo data and the observational data from the lightning location de- tection equipment as well as the meteorological data from regional automatic stations, the lightning characteristics in a heavy rainfall process caused by the southwest vortex on June 9,2011 in Hubei province were analyzed. The results indicate that the location of ground lightning differs in the different stages of mecoscale convective systems （MCS）. The frequencies of positive and negative lightning reach the peak values synchronously, which is one of the symbols of MCS mature. The intensive region of ground lightning and the rapid moving strong echo location of MCS are coincident. The ground lightning appears in strong echo region of MCS;they have a good relationship with radar echo between 45-55 dBz;the strong precipitation occurs in the disappearing stage of MCS. |
