| 英文摘要 | We have studied the physical processes leading to one triggered lightning flash using the altitude-triggering technique. The main characteristics of the triggered lightning are inferred from data of simultaneous electric field change measurements at two stations and highly time-resolved optical signals. The results reveal the characteristics of leading propagation to the triggered lightning. When the rocket attached with a thin steel wire is ascending to the height of several hundred meters, a typical bi-directional leader is initiated at the top and bottom end of the wire. When the negative leader propagating downward approaches to the ground, a positive connecting leader is excited from the ground and propagates upwards. The average speed of the negative and connecting positive leaders is around 0.86 x 10(5) M/S. A mini-return stroke is produced with the connection to the ground of downward negative leader. The upward positive leader initiated from the top end of wire propagates at a speed of about 1.1 x 10(5) m/s. |
