1 Introduction
Lightning resulted from an electrical spark due to tiny particles movements in either between the clouds (intercloud), between the separate charges in the same cloud (intracloud), between a cloud and the air, or between the cloud and the earth [1]–[7]. These tiny particles called electrons and they are part of atoms. Electrons have negative energy and move around the nucleus of atoms which with the positive charge resulting attraction between them. During a thunderstorm, some of the atoms lose their electrons while other atoms gain extra electrons. These phenomena usually occur inside a storm cloud. Extra electrons mean that the atoms have more negative energy. Wind carry atoms with fewer electrons into the storm cloud, and atoms with fewer electrons will stay on top of the cloud and vice versa. Electrons at the bottom of cloud will attract to the positive atoms on the top. These electrons will also attract with other positive atoms located in other cloud and on the ground. When these attractions become high enough, the electrons will suddenly shoot into the group of positive atoms [8]. Hence, lightning flashes occur [2].
