ASPERATUS! Beautiful and scary!

Meteorologists claim that nothing like they have not seen before. These clouds are similar whether on
stormy sea, or on the surface of the earth. They are dark, bizarre "dented". Of them stick out
swirling "horns". View - frightening. And sinister.
You need a lot of energy and heat to form clouds such amazing shape.
The British took the initiative to call education than ever before in the sky «Asperatus».
