Mammatus, Lenticular & Other Extreme Clouds

"Breast-clouds"

Mammatus Clouds, or "breast-clouds", are fascinating formations in the sky, made mostly from the cumulus cloud base. Although they are not a sign that a tornado is about to form, they often accompany tornado-producing storms, or even may be direct byproduct of tornado activity - an aftermath of severe thunderstorms. Thanks to the exclusive permission of Jorn Olsen, here are some weird mammatus shots:
