Abstract
The propagation effect of lightning-produced electromagnetic pulse over a large mountainous region in southern-west China has been investigated. The regional geometry data are adopted from a global digital elevation model named GTOPO30 with a horizontal resolution of 30 arc seconds and vertical accuracy of about 30 m. FDTD (Finite-difference time-domain method) is used to calculate the electromagnetic fields generated by lightning return strokes at various locations in the region. In comparison with a flat region, it is found that the topography of the region has large influences on the lightning - produced electromagnetic field waveforms and its propagation properties. Quantitative results of the simulation can be used to improve the performance of a lightning location network in mountainous region in terms of the lightning strength and location accuracy.
