Quizplus · Accepted Answer

The flickering appearance of a cloud-to-ground lightning discharge is due to the observer being able to barely distinguish separate return strokes within the lightning bolt. Each lightning strike can consist of multiple return strokes, which can give the appearance of flickering as each stroke follows rapidly one after the other.
