Severe Information: May 9, 4:55am 15 reviews •http://www.extremeinstability.com/sto...; An interesting site about storms and storm chasing. Also interesting is the young man who narrates his obsession (?) with this way of life.

Lenticular clouds

Technically known as altocumulus standing lenticularis, are stationary lens-shaped clouds that form at high altitudes, normally aligned at right-angles to the wind direction.

These clouds are formed by so-called "mountain waves" of air created by strong winds forced over high mountains. Then they hang over the mountains like alien "motherships"...

Mammatus
These are protrusions hanging down from the anvil cloud. They are rather common around severe storms and are not dangerous themselves. They form from turbulent sinking air motions.

They like to form upwind of the updraft more than they do downwind. The updraft is trying to force the clouds into the stronger winds aloft and essentially forces this to happen.
