摘　　要：该文基于全闪电定位系统,采用网格空间时间密度法对广州地区夏季一次雷暴活动的空间演变过程进行全闪电定位和空间演变过程分析,得到雷暴在不同时刻的扩散面积、主放电中心的坐标、移动速度、移动方向,并画出了地域演变图像。该雷暴为一次过境雷暴,雷暴起始时沿东北方向以平均67km/h的速度移动,移动过程中全闪电平均影响范围达258.5km^2,雷暴活动一段时间后,在广州南部发现另一处雷暴向北方移动,两处雷暴汇合后又分开向东边移动,后一处雷暴平均速度为14.72km/h,行进中全闪电平均影响范围达221.2km^2。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 258.5km^2.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 221.2km^2.
