2019年江西二维和三维地闪定位资料对比分析

Comparative Analysis of 2D and 3D Lightning LocationData in Jiangxi Province in 2019

基于2019年江西二维和三维地闪定位资料,从探测站点分布、时空分布、电流强度、电流陡度、地市密度分布、地闪空间分布等多方面,采用统计分析方法,对二维和三维地闪定位数据进行对比分析。结果表明:2种地闪定位资料监测雷电活动存在的一些差异,指出三维地闪定位资料的优势与不足,为三维地闪定位资料在江西雷电监测与应用业务化提供重要参考依据。

Based on the two-dimensional and three-dimensional lightning location data of Jiangxi Province in 2019,the two-dimensional and three-dimensional lightning location data are compared and analyzed by using statistical analysis method from the aspects of detection station distribution,space-time distribution,current intensity,current steepness,city density distribution,and lightning spatial distribution.The results show that there are some differences between the two kinds of lightning location data in monitoring lightning activity,and the advantages and disadvantages of three-dimensional lightning location data are pointed out,which provides an important reference for three-dimensional lightning location data in Jiangxi lightning monitoring and application.
