Ordinary Cell: As the name implies, this is a thunderstorm with only one cell. It's commonly referred to a 'pulse' thunderstorm. Multi-cell Cluster: These are thunderstorms that are organized in clusters of 2-4 short-lived cells. Multi-cell Line: Some thunderstorms will form in a line which can extend for hundreds or miles. These 'squall lines' can last for hours and cause a lot of damage. Super cell Thunderstorms: These are potentially the most dangerous form of all thunderstorms types. Super cell thunderstorms have produced numerous long-lived strong and violent (EF2-EF5) tornadoes, along with damaging wind, hail and flash floods.

16 million thunderstorms occur each year Divide the number of seconds between a flash of lighting and thunder claps by 5 to determine the distance the storm is in miles.
