Lightning occurs when regions of excess positive and negative charge develop within the cloud. Typically, there is a large volume of positive charge in the upper regions of the cloud, and a large negative charge in the center. . Thunderstorm structure. Thunderstorms are classified into four major types, namely the . supercell. , . squall . line, . multicell. . single . cell. .. The strongest type is called the . supercell. , which can be as wide as 24 kilometers . What is Severe Weather?.
