Definition: lighting -- phenomena / turbulence / cloud

Steps of process:

  1. Separate charges such a way that the negative charges concentrate in the base of the cloud.
  2. Push down negative charges on the ground away from the surface to leaving a net positive charge on the surface.
  3. Attract opposite charges, so the positive and negative charges are pulled toward each other.
  4. Connect negative and positive parts of stepped leader which make a conductive path from the cloud to the ground and the negative charges rush down it causing the visible stroke.
  5. Full channel that created by stepped leader with relatively static charge.
  6. Join two parts so do the charges near the join.
  7. Even though the charges are moving downward, travel visible stroke upwards with fast-moving charges which create light.

How Lighting Is Created


Lighting is a phenomenon that is created in cloud turbulence .the process of creating lighting includes the following steps. First, a charge is separated such a way that the negative charges concentrate in the base of the cloud, and negative charges are pushed down on the ground away from the surface to leaving a net positive charge on the surface Next, opposite charges are attracted so the positive and negative charges are pulled toward each other, and negative and positive parts of stepped leader are connect which make a conductive path from the cloud to the ground and the negative charges rush down it causing the visible stroke. After that, a channel that created is filled by stepped leader with relatively static charge, and two parts are joined so do the charges near the join. Finally, visible stroke is traveled upwards with fast-moving charges even though the charges are moving downward with fast-moving charges which create light.
