APOD 2.2: Mammatus Clouds Over Saskatchewan


I have never seen such bizarre looking clouds in a picture that has not been photoshopped- the clouds look like balloons/bags of air or jellyfish, or a woman's breasts, for which they are named after. They are called Mammatus clouds.

These cloud pockets occur when water and ice falls into clear air during evaporation. They are usually a precursor to extreme weather, and are accordingly perceived as an ominous sign- although they are beautiful and unique. They tend to appear in "turbulent air" if there is a thunderstorm nearby. They can extend for hundreds on miles.

The picture was photographed in Regina, Saskatchewan, Canada during the summer. The Mammatus clouds look especially dramatic because of the sunlight appearing on the side.
