flows from the ground up to the cloud). The reverse happens in a positive CG flash, where electrons travel upward along the lightning channel, while also a positive charge is transferred downward to the ground (the conventional current travels from cloud to ground).

Positive lightning is less common than negative lightning and on average makes up less than 5% of all lightning strikes.

There are a number of mechanisms theorized to result in the formation of positive lightning. These are mainly based on movement or intensification
