| 摘 要： | 电场强度预警应以电场强度到达的门限等级、电场曲线初始阶段是否有快变抖动为判断的标准,雷电距离预警以雷电发生的位置和电场仪之间的距离为参考。综合两种预警手段,并结合人工判断雷电的移动趋势、对预警提前时间的要求以及电场仪安装的位置和本地的地形条件等因素,实现更准确的雷电短时预警。

| Abstract: | Precaution of electric field intensity should base on its intensity threshold grade and fast time varying jitter of electric field curve.Forecast warning of lightning location can be judged on the distance between lightning's happening location and electric field instrument.Integrated these two precaution methods,combined with manual judgement on lightning's moving trend,the location of electric field instrument,and local landform,etc,we can succeed in more accurate and short-time lightning precaution. |

| Keywords: | location of lightning lightning early warning frequent dithering of electric field |
