Abstract

Based on the total lightning location system, this paper analyzes the spatial evolution process of a summer thunderstorm activity in Guangzhou city in detail by the grid space time density method. The spreading area, the main discharge center, the moving speed and the moving direction at different periods of the thunderstorm are obtained. The image of regional evolution is drawn showing that the thunderstorm is a transit thunderstorm. The initial thunderstorm moved at an average speed of 67km/h toward the northeast. The spreading area of the total lightning during the movement reached 258.5km². Another thunderstorm was found in southern Guangzhou moving northward after a period. After the two thunderstorms merged, they moved to the east separately. The average speed of the latter thunderstorm was 14.72km/h, and the spreading area during the movement reached 221.2km².

Key words： Thunderstorm activity lightning location system spatial evolution total lightning
