英文摘要 | A positive cloud-to-ground (+CG) lightning flash containing a single stroke with a peak current of approximately +310kA followed by a long continuing current triggered seven upward lightning flashes from tall structures. The flashes were observed on 4 June 2016 at the Tall Object Lightning Observatory in Guangzhou, Guangdong Province, China. The optical and electric field characteristics of these flashes were analyzed using synchronized two-station data from two high-speed video cameras, one total-sky lightning channel imager, two lightning channel imagers, and two sets of slow and fast electric field measuring systems. Three upward flashes were initiated sequentially in the field of view of high-speed video cameras. One of them was initiated approximately 0.35ms after the return stroke of +CG flash from the Canton Tower, the tallest structure within a 12-km radius of the +CG flash, while the other two upward flashes were initiated from two other, more distant tall objects, approximately 18ms after the +CG flash stroke. The initiation of the latter two upward flashes could be caused by the combined effect of the return stroke of +CG flash, its associated continuing current, and K process in the cloud. Each of these three upward flashes contained multiple downward leader/upward return stroke sequences, with the first leader/return stroke sequence of the second and third flashes occurring only after the completion of the last leader/return stroke sequence of the preceding flash. The total number of strokes in the three upward flashes was 13, and they occurred over approximately 1.5s. |
