摘要

Based on the images from the high-speed video camera systems, the statistics of the CG flashes was made in five different regions of the China. During the 11 years, 103 CG flashes were captured. 35.9% out of them had one stroke. The 21.4 % and 13.6 % had two and three return strokes,respectively. The average return stroke per flashes was 3.38. The average number of strokes per positive flashes was 12,while the average number of strokes per negative flashes was 3.48. 70.8% out of them had only strike point. 27.2 % of them have more than one strike points and the most is four. The average stroke point per flashes was 1.38. The time intervals between successive return strokes in a flash were ranged from 2 to 520 ms. Most of them ranged from 16 to 256 ms.
