Supercell thunderstorm forming over rural Nebraska,USA. A supercell thunderstorm is a severe long-lived storm within which the wind speed and direction changes with height. This produces a strong rotating updraft of warm air,known as a mesocyclone,and a separate downdraft of cold air. Tornadoes may form in the mesocyclone,in which case the storm is classified as a tornadic supercell thunderstorm. The storms also produce torrential rain and hail.
