摘  要：
通过对三维闪电定位系统数据进行处理和统计分析,研究2021年江苏省雷电活动和雷电灾害特征,结果表明:2021年江苏全省闪电以负闪为主,占地闪总数76.85%,大部分闪电强度小于60 kA.从月际分布来看,夏季为雷暴高发期,闪电主要集中在7-9月.2021年江苏省的初雷日出现在1月2日,较常年平均提前38 d,终雷日出现在12月31日,较常年平均推迟37 d;从地域分布来看,2021年闪电在全省范围总体呈现南多北少的分布,密度高值区集中在沿淮及苏南部分地区.雷灾地域分布不均匀,苏南地区雷电灾害较多,家用电子设备损毁最严重,其次为办公电子设备受损.2021年江苏省雷电活动规律以及雷灾分布特征可为防雷减灾工作的开展提供重要参考.

摘  要：
Through the processing and statistical analysis of data from the 3D lightning positioning system,the characteristics of lightning activities and disasters in Jiangsu Province in 2021 were studied.The results showed that in 2021,the lightning in Jiangsu Province was mainly negative,with a total area of 76.85%and most lightning intensities less than 60kA.From the perspective of monthly distribution,summer was the peak period for thunderstorms,with lightning mainly concentrated from July to September.The initial thunderstorm day in Jiangsu Province in 2021 occurred on January 2,38 days earlier than the annual average,and the final thunderstorm day occurred on December 31,37 days later than the annual average;From the perspective of regional distribution,in 2021,lightning showed an overall distribution of more in the south and less in the north throughout the province,with high density areas concentrated in some areas along the Huaihe River and southern Jiangsu.The distribution of lightning disasters was uneven,and there are many lightning disasters in the southern region of Jiangsu.The damage to household electronic equipment was the most severe,followed by damage to office electronic equipment.The regularity of lightning activities and the distribution characteristics of lightning disasters in Jiangsu Province in 2021 can provide important references for the development of lightning protection and disaster reduction work.
