    Characteristics analysis of lightning disaster in Beijing from 2005 to 2014

    • 摘要: 利用2005-2014年北京市雷电灾害资料和2008-2014年北京市ADTD闪电定位资料,统计分析了北京市雷电灾害和闪电的特征。结果表明:2005-2014年北京市有记录的雷电灾害共532起,年平均雷电灾害为53.2起,年平均直接经济损失超过300万元。北京市雷电灾害主要发生在6-8月,其中6月雷电灾害发生最多;雷电灾害主要集中出现在17-23时,其中19时雷电灾害出现最多。北京市城六区和顺义等地区雷电灾害密度较大,总体呈城区多、郊区少,南部多、北部少的特征。雷电灾害主要发生在民用、企业、五大行业(交通、电力、通信、石化、金融)和旅游等行业,雷电灾害对象主要为办公电子电器(54.12%)和家用电子电器(30.47%),雷电灾害主要发生在生活场所、办公场所及生产场所。雷电灾害和自然闪电时间分布基本吻合,二者空间密度略有差异。

       

      Abstract: Using lightning disaster data from 2005 to 2014 and ADTD (Active Divectory Topology Diagrammer) lightning location data from 2008 to 2014 in Beijing,the characteristics of lightning disaster and lightning were analyzed based on statistic approaches.The results show that there are totally 532 cases of lightning disasters from 2005 to 2014,with an average of 53.2 cases per year in Beijing.The annual direct economic losses are more than three million yuan.The lightning disaster mainly occurs during June to August,especially in June,mostly happening at 17:00 to 23:00,especially at 19:00.The spatial distribution of lightning disaster demonstrates that there is a higher value in the urban and southern parts and lower in the suburb and northern parts.The lightning disaster primarily happens in the civilian,business,transportation,electric power,communication,petrochemical,finance,and tourism industries.The victims of lightning disaster generally include office (54.12%) and household (30.47%) electronic appliances.The lightning disasters usually focus on the living,office and production spaces.The temporal distribution of lightning disaster is basically consistent with that of the lightning,while the spatial density distributions of them are a little different.
