| 摘 要： | 利用贵州省三维闪电定位资料、C波段Doppler天气雷达资料及探空资料对2017年贵州一次强天气过程中闪电特征及雷达回波特征的相关性进行分析。结果表明：回波顶高与闪电频数的相关性优于回波强度与闪电频次的相关性；不同温度层上,大于等于30dBz的回波面积与总闪频次和负地闪频次相关性都比较好,其中零度层高度上大于等于30dBz的回波面积与总闪频次相关性最好,且多项式拟合效果优于线性拟合；最大回波强度 、回波顶高 以及30dBz强度回波发展高度对闪电的发生具有一定的指示意义。

| Abstract: | Based on the three dimensional lightning location systerm, Doppler weather radar data and radiosonde data in Guizhou, analyzed the correlation between lightning characteristics and radar echo characteristics in a strong weather process in Guizhou. The results show that the correlation between the top layer of ech and lightning frequency is better than that between echo intensity and lightning frequency; The echo area that greater than or equal to 30dBz tends better correlation with total lightning frequency and negative lightning frequency in different temperature layer , in the zero layer, correlation between echo area greater than or equal to the 30dBz and total lightning frequency is thebest,well, polynomial fitting is better than the linear fitting;The maximum echo intensity, echo top height, the development height of 30dBz is an indicator of the occurrence of lightning. |
