| 摘 要： | 应用山东省闪电定位系统资料,分别统计了正、负闪雷电流幅值的分布特征,并应用matlab软件得到了正、负地闪的经验累积分布、雷击次数等值线图以及高于90 kA电流的落雷位置。结果表明,负地闪发生的几率明显高于正地闪,正地闪幅值的最大值、最小值、平均值以及中值电流要高于负地闪;正地闪的平均能量高于负地闪,较高幅值的雷电流并不一定发生在落雷密度高的区域,对于雷击密度小的区域也应重视。

| Abstract: | Lightning positioning system data in Shandong Province were used to analyze distribution characteristics of lightning current amplitude, matlab software was adopted to obtain the positive and negative experience cumulative distribution of current amplitude and the position of more than 90 kA. The resuhs showed most cloud-to-ground flashes are negative; Positive current amplitude of the maximum, minimum, av- erage, and the median current is higher than the negative lightning. It should be attention in lewer lightning activity. |
