Abstract:
By use of Chongqing lightning location data from 2007 to 2016 and the digital elevation model of this region, applying the GIS spatial analysis and mathematical and statistical methods, an analysis is made of the influence of topography on main lightning hazard factors. The results show that the altitude and slope direction have an impact on the CloudtoGround (CG) flash density, and the slope has a negative correlation with the CG flash density. The distribution of the ground flash intensity between different slope directions has obvious differences, and the altitude, slope and CG flash intensity are not correlated.
