基于雷电易发评价体系下的广西雷电区划

利用1960-2013年广西地面气象站观测雷暴资料、2009-2018年二维雷电监测定位资料和2016-2018年三维雷电定位监测资料,以闪电密度为评估要素,建立层次分析模型,绘制广西雷电易发区划图;并加载环境高程数据、2000-2019年雷灾数据以及2005年—2018年广西人口、GDP统计资料,计算雷电灾害风险值,...

Lightning division of Guangxi based on the evaluation system of lightning proneness

Using Guangxi ground weather station observational thunderstorm data from 1960 to 2013,two-dimensional lightning monitoring positioning data from 2009 to 2018,and three-dimensional lightning positioning monitoring data from 2016 to 2018,an analytic hierarchy process model was established with the lightning density as the evaluation element,and the lightning susceptibility zoning map of Guangxi was drawn.The results showed that the lightning-prone areas in Guangxi were divided into three levels:extremely high-prone areas,high-prone areas,and medium-prone areas.The medium-prone areas were the main areas,accounting for 47%of Guangxi;the extremely high-prone areas were mainly distributed in southern Guangxi,southeastern Guangxi and eastern Guangxi.Lightning disaster risk in Guangxi was divided into three grades:extremely high risk,high risk and medium risk.Most areas were medium risk.The lightning disaster risk zoning in Guangxi was basically consistent with the distribution of lightning-prone areas,and the grade change trend was decreasing from the coast to the inland.
