摘　　要：闪电是引起输电线路跳闸的重要原因之一,准确的探测及预测闪电发生区域对于保障电网安全稳定运行具有重要意义。本文利用风云四号闪电成像仪(LMI)数据对云南高原地区闪电探测效果进行评估,可以得出,云顶亮温与雷电发生区域存在着相关性,并通过统计得出LMI数据探测的闪电总数为地基闪电探测的30%左右。Lightning is one of the important causes of transmission line trip.Accurate detection and prediction of lightning occurrence area is of great significance to ensure the safe and stable operation of power grid.This paper evaluates the lightning detection effect of Yunnan Plateau from August by using the data of FY-4 lightning imager(LMI).It can be concluded that there is a correlation between the cloud top brightness temperature and the lightning occurrence area,and the total number of lightning detected by LMI data is about 30%of the ground-based lightning detection.

关 键 词：闪电成像仪 地基闪电探测 云南高原地区
