摘要: 利用2007—2016年湖北省雷电监测资料,分析选取了地闪密度、雷电流陡度以及小电流百分比作为雷电危害强度等级区划的因子。采用投影寻踪确定了各因子的权重与雷电危害强度等级区划模型。利用自然断点法将雷电危害强度划分为I级至IV级,并绘制了湖北省雷电危害强度等级分布图,整体而言,全省雷电危害强度大致从西北向东南逐级增强。

关键词: 地闪密度, 雷电流陡度, 小电流百分比, 雷电危害强度, 湖北省

Abstract: Ground flash density, lightning current steepness and small current percentage were selected as the indexes to classify lightning hazard intensity by using the lightning detection data from 2007 to 2016 in Hubei province. The weight of each index and the classification model of lightning hazard intensity were determined by projection tracking. By using the natural breakpoint method, the lightning hazard intensity was divided into grade I to IV, and the distribution map of lightning hazard intensity in Hubei province was drawn. Overall, the lightning hazard intensity in the whole province increased from northwest to southeast.

Key words: ground flash density, lightning current steepness, small current percentage, lightning hazard intensity, Hubei province
