 Single-cell thunderstorms form in environments of low vertical wind shear and last only 20–30 minutes.Organized thunderstorms and thunderstorm clusters/lines can have longer life cycles as they form in environments of significant vertical wind shear, normally greater than in the lowest of the troposphere, which aids the development of stronger updrafts as well as various forms of severe weather.The supercell is the strongest of the thunderstorms, most commonly associated with large hail, high winds, and tornado formation.
