Supercell thunderstorm. Lightning strike within a supercell thunderstorm. Supercell thunderstorms are severe long-lived storms 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. These storms also produce torrential rain and hail.
