摘要
文章利用ADTD型闪电定位系统2014-2020年的云地闪资料,分析了兴安盟地区闪电的时空分布规律和活动特征。文章介绍了资料来源和资料的预处理,并对闪电活动的年、月、日变化特征以及闪电密度、雷电流强度特征进行了详细分析,所得结论以期为提高雷暴等灾害性天气的预报预警水平提供理论支撑。
Based on the cloud-to-ground lightning data of ADTD lightning positioning system from 2014 to 2020,this paper analyzes the spatial and temporal distribution regularities and activity characteristics of lightning in Hinggan League area.This paper introduces the data sources and data preprocessing.And the annual, monthly and daily variation characteristics of lightning activity, as well as the characteristics of lightning density and lightning current intensity are analyzed in detail.The conclusions are expected to provide theoretical support for improving the forecasting and warning level of thunderstorm and other severe weather.
