Video Clip SS2935432 (Supercell Thunderstorm, timelapse)

Timelapse footage of a Supercell thunderstorm with multiple lightning flashes. 

A supercell is a large rotating storm system that often produces heavy rain, hail and sometimes tornadoes. The supercell is centred on a very powerful updraft, which lifts warm, moist air to high altitude. It cools as it rises, condensing and falling as precipitation. 

The base of the cloud is marked by a shelf cloud extending forwards, and a low wall cloud at the updraft/downdraft interface. This supercell was filmed in Kansas, USA, in June 2015. Such storms are most common in this region in spring and early summer.

Supercells are often put into three classification types: Classic, Low-precipitation (LP), and High-precipitation (HP). 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 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 and in the Tornado Corridor of Argentina, Uruguay and southern Brazil.
