摘要
利用贵州省闪电定位系统资料,对2010 ～2013年发生在黔西南州的闪电从年变化、月变化和雷电流强度等多个角度进行综合分析,找出发生在黔西南州雷电的分布特征和活动规律.结果表明,2010 ～2013年黔西南州闪电以负闪为主,占总闪电数的96.2％,正闪电次数较少,占总闪电数的3.8％;近4年黔西南州雷电主要发生在4 ～ 10月,峰值较高为5～8月,11月～次年3月雷电发生很少;负闪电分布基本与总闪电一致;近4年黔西南州最大正闪电强度为249.90 kA,最大负闪强度-249.95 kA,平均正闪电强度54.21 kA,平均负闪强度-34.82 kA,强度在100 kA以上的有3 779次.
Abstract
Using lightening location system in Guizhou Province,the annual variation,monthly variation and current intensity of lightening in Qianxinan Prefecture during 2010-2013 were comprehensively analyzed,the distribution features and activities law were obtained.The results showed that lightening in Qianxinan Prefecture during 2010-2013 were dominated by negative lightening,accounting for 96.2％,while positive lightening accounting for 3.8％;lightening mainly occurred during Apr.-Oct.,peak was higher from May to Aug.,and there was little lightening from Nov.to Mar.of the following year;the distribution of negative lighting was consistent with total lightening;the maximum positive and negative lightening intensity were 249.90,-249.95 kA respectively,the average positive and negative lightening intensity were 54.21,-34.82 kA respectively,the lightening intensity above 100 kA had 3 779 times.
