Intra-cloud lightning effect in Clearwater Florida natural phenomenon bright thunders

Lightning is a natural phenomenon formed by electrostatic discharges through the atmosphere between two electrically charged regions, either both in the atmosphere or one in the atmosphere and one on the ground, temporarily neutralizing these in a near-instantaneous release of an average of between 200 megajoules and 7 gigajoules of energy, depending on the type.

Intra-cloud lightning is the most common type of lightning and occurs when there is an electrical discharge between oppositely charged areas within a thunderstorm cloud.

Intra-cloud lightning can appear as a sheet of light that lights up the sky. It can also sometimes exit the cloud and appear as a bright channel that can be visible for miles.
