摘要
从云地闪频度、强度和云地闪自身特性等方面对区域云地闪分布规律进行分析和研究,表明陕西云地闪的基础参数可反映本地区落雷程度的差异,将地面落雷密度、雷电流幅值概率分布应用于防雷计算更符合区域云地闪活动实际状况。雷电流幅值比率及云地闪参数特征对比分析,确定了陕西多雷区的分布特征及雷电活动规律。
The paper analyzes and studies the distribution law for cloud-to-ground lightning in Shaanxi area from three aspects of cloud-to-ground lightning frequency, intensity and characteristics. The research shows that the basic parameters of Shaanxi cloud-to- ground lightning can reflect the differences in local lightning strike density; the lightning strike density and lightning current amplitude probability distribution can be applied to the calculation for lightning protection, it is much more in line with the actual situation of regional cloud-to-ground lightning activities; the distribution characteristics of Shaanxi high thunderstorm region and the law of the lightning activities are confirmed by the comparative analysis of the lightning current amplitude ratio and cloud-to-ground lightning characteristics.
