| 摘 要： | 利用闪电定位资料,对广西地区闪电活动的时间、强度和空间分布特征进行了分析。结果表明:闪电主要集中在春末仲夏发生,4-9月是闪电高发期(约占全年总闪电活动的98.33%),闪电活动绝大多数发生在午后至傍晚时分;云地闪电中负闪占绝大多数,正闪的平均强度大于负闪;闪电密度高值区主要位于桂东南、北部湾沿海地区和十万大山迎风面,闪电的空间分布差异与地形和水汽条件有很大关系。同时,根据2008年广西雷电灾害事例,分析了雷电灾害的特点和原因。

| Abstract: | The spatiotemporal distribution and intensity of lightning activities in Guangxi Province were studied by using lightning data collected by twelve-stations with lightning detection and location network in the province.The result indicates that the end of spring and mid-summer are the main lightning activity periods,about 98.33% of the lightning flashes in a year occurs frequently from April to September,and lightning activities primarily occur between afternoon and early evening.Major cloud-to-ground flashe... |
