From: Leader-chasing behavior in negative artificial triggered lightning flashes
The illustration of the path along which the chasing leader II propagated and the speculative structure of the channel out of the high-speed camera’s FOV. (a) A sequence of cropped high-speed frames showing the propagation of Dart leader 8, with background removed, intensity inverted, and contrast enhanced. Some areas in Frames 1 to 5 were colored with contrast further enhanced. (b) A processed frame showing the path for the leaders. The blue rectangle indicates the high-speed camera’s FOV, the orange arrows indicate the path of the chased leader II, and the purple arrows indicate the path of the chasing leader II. A photo with higher image resolution recording the twisted portion of the channel is shown.
