The start of lightning: Evidence of bidirectional lightning initiation

Scientific Reports, 2015
AbstractLightning flashes are known to initiate in regions of strong electric fields inside thunderstorms, between layers of positively and negatively charged precipitation particles. For that reason, lightning inception is typically hidden from sight of camera systems used in research.
