Supercells are one of the few types of clouds that typically spawn tornadoes within the mesocyclone, although only 30% or fewer do so. They usually produce copious amounts of hail, torrential rainfall, strong winds, and substantial downbursts. ![]() Supercells can be any size – large or small, low or high topped. Supercells can sometimes develop two separate updrafts with opposing rotations, which splits the storm into two supercells: one left-mover and one right-mover. If they track to the right or left of the mean wind (relative to the vertical wind shear), they are said to be "right-movers" or "left-movers," respectively. Supercells have the capability to deviate from the mean wind. Because they can last for hours, they are known as quasi-steady-state storms. Typically, supercells are found in the warm sector of a low pressure system propagating generally in a north easterly direction in line with the cold front of the low pressure system. Supercells are usually found isolated from other thunderstorms, although they can sometimes be embedded in a squall line. A high number of supercells are seen in many parts of Europe as well as in the Tornado Corridor of Argentina, Uruguay and southern Brazil. Supercells can occur anywhere in the world under the right pre-existing weather conditions, but they are most common in the Great Plains of the United States in an area known as Tornado Alley. LP supercells are usually found in climates that are more arid, such as the high plains of the United States, and HP supercells are most often found in moist climates. Supercells are often put into three classification types: classic (Normal precipitation level), low-precipitation (LP), and high-precipitation (HP). Supercells are often isolated from other thunderstorms, and can dominate the local weather up to 32 kilometres (20 mi) away. 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. Due to this, these storms are sometimes referred to as rotating thunderstorms. While many ordinary thunderstorms (squall line, single-cell, multi-cell) are similar in appearance, supercells are distinguishable by their large-scale rotation.Ī supercell is a thunderstorm characterized by the presence of a mesocyclone: a deep, persistently rotating updraft.
