英文摘要 | The processes of return-stroke and the intracloud discharge just before the first return stroke have been analyzed by using the data from a high-speed digital camera (1000 frames/s), slow antenna, fast antenna and VHF wide-band interferometer in Nagqu, the Qinghai-Xizang Plateau. The results suggest that the intracloud process occurred between the lower positive charge region and the middle negative charge region below the cloud. The negative charge region was located at about 2.8 similar to 4.5 km above the ground. The region of discharge initiation in the cloud was about 1.0 similar to 1.7 kin above the ground. The initial streamer of discharge showed several horizontal branches when it progressed out of the cloud body. The velocity of stepped leader was estimated to be about 1 X 10(5) m/s. During its propagation to the ground, the leader channel showed a bigger curl. The first return stroke of the lightning had no difference with that in the lower altitude regions, and its current peak value was about 24.1 kA. But the subsequent strokes were quite weak on the Plateau. |
