Abstract
Using the Huaian region lightning location data from 2011 to 2014,this paper analyzed lightning frequency,time distribution of lightning,lightning spatial variation characteristics of Huaian region.The results showed that Huaian region was given priority to with negative lightning,accounted for 90%;the lightning activities had significant differences,lightning mainly concentrated in June to Sepember,accounted for 96%of the total number lightning;the peak period of the lightning activities was 1400-1800 in the afternoon,the trend of negative flash and total flash was consistent,the number of positive flash change unobviously;Lightning density larger areas were mainly concentrated in the southern and eastern regions;The average density of lightning was 2.39 times per square kiolmeters every year;The total flash intensity focused on 10~40 kA;Lightning strength greater than 32 kA cumulative probability was less than 50%.关键词
