Here is my weekly weather quiz question for the last time. What is a “Lightning Channel? Here is the correct answer. A Lightning Channel is the irregular path through the air along which a lightning discharge occurs. A typical discharge of flash between the ground and the cloud is actually a composite flash which is composed of several sequential lightning strokes, each of which is initiated by a leader and terminated by a return streamer.
