1971—2008年青岛地区雷电时空分布特征
Temporal and spatial distributions characteristics of thunderstorm and lightning from 1971 to 2008 in Qingdao,Shandong province
摘要
Abstract
Based on the thunderstorm data in 7 observational stations from 1971 to 2008 and lightning monitoring data from lightning location system from 2006 to 2009 in Qingdao,the temporal and spatial distributions characteristics of thunderstorm were analyzed.The distribution characteristics of lightning in this region were also analyzed for a large scale petrochemical project as an example.The results indicate that thunderstorm days increase from the southeast to the northwest of Qingdao.Seasonal variations of thunderstorm are obvious,and most thunderstorms appear in July and August.According to the lightning location data,the distributions of current intensity of lightning and the accumulative probability of lightning current near the place of petrochemical project are obtained using a relative analysis software,and the corresponding current intensity values of lightning are also obtained.It is found that the largest value in this region is 41.68 kA.Lightning density Ng calculated by lightning data from lightning location system is more objective than that calculated by artificial observational data.The results could provide parameters for thunderstorm and lightning disaster assessment.关键词
