摘要
文章利用多普勒天气雷达及闪电定位资料对2019-04-26发生于闽西南连续两次降雹过程的闪电活动演变特征进行了研究分析,首先介绍了资料来源和分析方法,对天气环流背景进行了说明;然后对闪电活动特征中的时空分布特征、闪电与雷达回波之间的关系和闪电频数、强度随时间变化进行了详细地分析;最后得出结论,以期为强对流天气的临近预报提供参考。
Based on Doppler weather radar data and lightning location data,this paper studies and analyzes the evolution characteristics of lightning activity during two consecutive hailstorms occurred in southwestern Fujia on April 26,2019.Firstly,the data sources and analysis methods are introduced,and the background of synoptic circulation is explained.Then,the temporal and spatial distribution of lightning activity characteristics,the relationship between lightning and radar echo,and the variation of lightning frequency and intensity with time are analyzed in detail.Finally,the conclusion is expected to provide reference for the forecast of severe convective weather.
