Study of Ground Flash Density

Abstract

Ground flash density (flashs/km2 /year) can reflect the activity of lightning exactly, so it was presented in this paper as a principle to show the thunder distribution in Chongqing region. Based on this principle, thunderstorm distribution electronic map of Chongqing region was programmed, using the data accumulated by the lightning location system in recent years. And this electronic map will be used in the lightning-proof of power transmission lines.
