山东省闪电分布及雷电灾害特征分析
Analysis of lightning distribution and lightning strike disaster characteristics in Shandong
摘要
Abstract
The characteristics of cloud-to-ground (CG) lightning distribution in Shandong Province is analyzed by using the lightning data from LD-II lightning location system in 2010. It is found that the majority of CG lightning is negative CG flashes, and the lightning flashes occur more frequently from June to August in summer and from 15:00 to 22:00 in a day. The average current intensity of CG flashes is about 11. 83 kA. The current intensity of positive flashes is mainly focused on the range of 15~40 kA, and the current intensity of negative flashes is mainly focused on the range of 0~25 kA. The average density of CG flashes in Shandong is 2. 97 fl ? Km-2 ? A-1. The average annual thunderstorm days are 19. 48. According to the latest date from the meteorological department in Shandong, the number of lightning disasters occurred between June and August accounts for 83. 82% of the total amount. Electrical apparatuses are major targets damaged by thunderstrokes, and the e-lectric power industry occupy first place in all accidents caused by thunderstrokes.关键词
