Representative Elementary Area is introduced to replace grid-based lighting density. In consideration of lighting zonal distribution, elliptic field is taken as a representativ elementary area depending on least square method, varimax rotation and coordinate transformation.
利用雷电资料,引入表征面域,取代栅格型的闪电密度表示,结合雷电的带状性分布,利用最小二乘法、方差极大旋转和坐标转换,将表征面域取为椭圆域,计算出椭圆表征面域上的闪电密度。
