The temporal and spatial distribution characteristics of lightning activity,including thunderstorm days,regional lightning activity and cloud-to-ground flash frequency,are analyzed based on data of Jiangsu province in 2011.The distribution characteristics and types of lightning disasters are also analyzed.The results are as follows.The peak value of lightning activities in 2011 appeared in August when 11 thunderstorm processes occurred,which were more than in past years,and there were 2 large scale thunderstorm processes in November,which were very rare in previous records.The lightning activities were generally more in the south and less in the north in Jiangsu province,and the high incidence areas of thunderstorm are the south region between the Yangtze River and the Huaihe River and the main region of the middle and east of south Jiangsu province.The lightning disasters occurred mainly between June and August,and the office electronic equipments damage cases were the biggest and the household electronic equipments damage cases were the second types of lightning disaster,and 85% of lightning casualties were in the rural areas.At last,the paper proposes the countermeasures and suggestions for lightning disaster prevention,and provides a reference for the lightning disaster prevention work of Jiangsu province.
