Observations of multiple upward lightning flashes triggered by a positive cloud to ground flash

摘要：

　　A positive cloud-to-ground (+CG) lightning flash containing a single stroke followed by 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 (TOLOG), Guangdong Province, China.Three upward flashes were initiated sequentially in the field of view (FOV) of high-speed video cameras.One of them was initiated approximately 0.35 ms after the return stroke of +CG flash from the Canton Tower, the tallest structure within 12 km radius of the +CG flash, while the other two upward flashes were initiated from two other, more distant tall objects, approximately 18 ms after the +CG flash stroke.
