Tardive dysmentia

Supercell is a type of thunderstorm characterized by the presence of a mesocyclone: a deep, persistently rotating updraft. For this reason, these storms are sometimes referred to as rotating thunderstorms. Of the four classifications of thunderstorms (supercell, squall line, multi-cell, and single-cell), supercells are the overall least common and have the potential to be the most severe.

Characteristics

Supercells are often isolated from other thunderstorms, and can dominate the local climate up to 32 kilometres (20 mi) away. They have a unique internal structure that allows them to sustain themselves for many hours, and can produce severe weather such as tornadoes, damaging winds, large hail, and flash floods.

Types of Supercells

There are four types of supercells: Classic, Low-precipitation (LP), High-precipitation (HP), and Mini. The strongest tornadoes are most often produced by LP supercells, and HP supercells can also produce tornadoes, along with damaging hail and flash floods.

Formation

Supercells form in environments with strong vertical wind shear and sufficient instability. This combination allows the storm to rotate, which sets it apart from most other types of thunderstorms.

Hazards

Supercells can produce severe weather, including large hail, damaging winds, and tornadoes. They can also lead to flash flooding.
