Cui Xun et al（Jiangsu Meteorological Disaster Prevention Technology Center， Nanjing， Jiangsu 210041）

Abstract 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.
