Supercell thunderstorm and mammatus clouds (foreground) over countryside near Flagler, Colorado, USA. Mammatus clouds have a pouch-like appearance and form in the presence of sinking air. These clouds are associated with turbulent and stormy weather.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. Photographed on 8th June 2019. | |
