Explanation:
Is that a spaceship or a cloud?
Although it may seem like an
alien mothership,
it's actually a impressive thunderstorm cloud called a
supercell.
Such colossal storm systems center on
mesocyclones --
rotating updrafts that can span several kilometers and deliver
torrential rain and high winds including
tornadoes.
Jagged sculptured clouds adorn the supercell's
edge, while wind swept dust and rain
dominate the center.
A tree waits
patiently in the foreground.
The above supercell cloud was photographed in July west of
Glasgow,
Montana,
USA, caused minor damage, and lasted several hours before moving on.
