Abstract :
Current cutoff in lightning channels is an essential part of the lifecycle of all types of lightning flashes, and plays a pivotal role in the way a lightning flash develops. Yet it has not been seriously investigated, and is still poorly understood. We review the factors that affect changes in the current of leaders of both polarities, and examine and evaluate two recent hypotheses of the current cutoff mechanism.
