回击参数对闪电电磁场的影响

The Effect of Parameters of Lightning Return Stroke on Electromagnetic Field

基于 MTL L 闪电回击模型研究了不同回击速度和回击通道高度对不同场区的回击电磁场的影响。结果表明 ,通道高度在 (1～几十 ) km的范围内时对地面电磁场影响比较小 ,而回击速度对电磁场的影响比较明显。

Based on MTLL lightning return stroke model, the effect of lightning return stroke parameters on LEMP of different domain is researched. The result shows that the effect of the change of lightning channel length is little, but the effect of the change of return stroke velocity is distinct.
