Detailed explanation-1: -Lightning Detection Networks These two systems work by detecting radio waves (sferics) emitted by fast electric currents (strokes) in lightning channels. A “stroke” can be a fast current within the cloud, or a “return stroke” in a channel to ground.
Detailed explanation-2: -The answer is both. Cloud-to-ground (CG) lightning comes from the sky down, but the part you see comes from the ground up. A typical cloud-to-ground flash lowers a path of negative electricity (that we cannot see) towards the ground in a series of spurts.
Detailed explanation-3: -Cloud-to-Ground (CG) Lightning. In CG lightning, a channel of negative charge, called a stepped leader, will zigzag downward in a ‘forked’ pattern-hence it is sometimes called forked lightning. This stepped leader is invisible to the human eye and travels to the ground in a millisecond.
