The area with the most thunderstorm weather in Zhejiang

Lightning disaster is one of the ten most serious natural disasters, and our province is a region with high incidence of thunderstorms, and lightning strikes are on the rise. Yesterday, the lightning monitoring data of Zhejiang Province in 2008 released by the Provincial Meteorological Bureau and the Provincial Lightning Protection Center showed that there were more than 400,000 lightning strikes in our province last year, and the next March is likely to be a lightning-prone period. Last year, lightning struck Lishui 4 18 138. Judging from the total number of lightning in each region, Lishui is the largest, accounting for 65,660 times, accounting for 15.70% of the whole province, followed by Taizhou, accounting for 13.06%. Zhoushan has at least 1875 times, accounting for only 0.45% of the whole province, followed by Jiaxing. According to the statistics of lightning number in various districts and counties, Zhuji, Linhai, Yongjia, Huangyan, Longquan, Fuyang, Qingtian, Fenghua, Wuyi and Jiangshan rank first 10. The total number of lightning flashes in Zhuji ranked first is 283 15. Experts from the provincial lightning protection center said that the reason for this difference is not only the uneven occurrence of lightning caused by different factors such as climate, geology, geography and environment, but also the size of the regional area. Last year, the lightning in Zhejiang Province was mainly concentrated in June, 783 months, and the total number of lightning in three months was 358,329, accounting for 85.07% of the total lightning in the whole year, of which 26,550 lightning occurred on June 2 1 day, the highest in the whole year. Experts say that our province is in a subtropical monsoon climate. In the next three months, convective activities will be strengthened, and thunderstorms will be relatively frequent, leading to an increase in lightning. From the overall trend, lightning rarely occurs in June-March in our province, with obvious signs of increase in April, reaching a peak in June-August, beginning to decline obviously in September, and rarely occurs in June-February. From the analysis of lightning cycle, lightning mainly concentrates in the range of 12 ~ 2 1, and the number of lightning in this range is 369,429, accounting for 88.35% of the total lightning. However, the frequency between 4:00- 10 is relatively small, accounting for 6774 times, accounting for 1.62% of the total lightning. Last year, there were 83 lightning casualties. According to the reported disaster statistics, there were 50 lightning casualties in our province last year, with 35 injured and 48 dead, including 8 in Ningbo, 2 injured and 8 dead. Jinhua and Wenzhou had the most deaths, with 10 and 9 people respectively, while Zhoushan and Quzhou had no casualties. The analysis shows that there are relatively many casualties in farmland and simple houses, and almost all the deaths of lightning victims occur in rural areas, so the lightning protection work in rural areas needs to be strengthened urgently. Last year, there were 155 cases of building damage, 602 cases of office electronic and electrical equipment damage and 1270 cases of household electronic and electrical equipment damage caused by lightning disasters in the whole province. In the industry classification statistics, electricity and communication account for the bulk, accounting for 27.7% and 35.7% respectively.
