摘要
基于2014—2018年国家地基雷电探测网(ADTD)的闪电观测数据,对广西壮族自治区闪电时空分布进行研究。研究表明,闪电密度高值区主要集中在广西东南部(呈贺州-钦州的东北-西南走向)以及百色市西部;季节性分布特征明显,主要出现在4-9月,占总数的95.2%,6月雷电活动最频繁;闪电活动日高发时段为13-19时,峰值为16-17时;地闪中负闪占绝大多数。
This paper,based on the lightning observation data of the ADTD lightning location system during 2014 to 2018,studies the temporal and spatial distribution of lightning in Guangxi Zhuang Autonomous Region.The results show that the high value areas of lightning density are mainly concentrated in the southeast of Guangxi(northeast-southwest trend of Hezhou-Qinzhou)and the west of BaiseCity;The seasonal distribution characteristics are obvious,mainly from April to September,accounting for 95.2% of the total,and the lightning activity is the most frequent in June;The high incidence period of lightning activity day is 13:00-19:00,and the peak value is 16:00-17:00;The negative lightning flashes accounts for the vast majority of ground lightning.
