How Lightning Is Produced

Lightning is a phenomena that occurs during a storm. The process of producing lightning involves a number of steps. First, the charges are separated by the turbulence in the cloud in a way that the negative charges concentrate in the base of the cloud. Next, some of the negative charges are pushed down away from the surface, and a net positive charge is left on the surface. After that, the positive and negative charges are pulled toward each other, but the negative charges are smaller than the positive charges, so they move easily and cover most of the distance, and the invisible stroke thah is called a stepped leader is formed. After, the negative and positive parts of the stepped leader are connected in a conductive path from the cloud to the ground, and the negative charges are rushed down the ground and caused visible stroke. Finally, when the two parts are joined, the charges near them are also joined, and since it is the fast moving charges that creat the light, the visible stroke is rushed upward, even though the charges are moved downward.
