Cloud-to-Ground Lightning
Cloud-to-Ground Lightning : A lightning flash occurring between a charge center (either negative or positive) in the cloud and the ground. The cloud-to-ground discharge is initiated by a downward spreading leader followed by an extremely intense upward moving return stroke that is the prime source of glow. A cloud-to-ground discharge is usually a multipart event, called a flash, composed of several distinct sequences of a leader stroke followed immediately by a return stroke, the majority using the same path and following each other by a few hundredths of a second.
