A Supercell Storm Cloud Forming over Wyoming
Explanation: How do supercell storm clouds form?
Pictured above is a time-lapse video taken last Sunday detailing the formation of one such violent supercell in
eastern Wyoming,
USA. Starting as part of a large and dark thunderstorm complex, the
supercell comes together along with a large rotating updraft of air known as a
mesocyclone.
Mesocyclones form during rapid changes in wind speed and direction with height and can produce
torrential rain,
damaging hail,
swirling winds, and sometimes tornadoes. Storm watchers are seen studying, imaging, and ultimately running from the
developing storm cloud during the video. During the middle part of the video, the kilometer-wide
supercell can be seen swirling ominously with a nearly
flat bottom. Toward the end of the video, another swirling
supercell cloud forms but then quickly dissipates.
