Just a few hours ago, on April 20, 2016, a mammatus invasion started in the sky of Moscow, Russia.
I don’t know if some little green guys came down to Earth, but this sky looks really alien to me!
A mammatus wall engulfed the sky of Moscow on April 20, 2016, baffling sky watchers and residents.
No, there was no escape possible!
That looks really omnious and kind of beautiful also.
Mammatus clouds are some of the most unusual and distinctive clouds formations.
Look at this series of bulges or pouches emerging through the base of the cloud. Strange!
Mammatus clouds are usually formed in association with large cumulonimbus clouds.
In particular when these are forming large thunderstorms.
Sometimes very ominous in appearance, mammatus clouds are harmless and do not mean that a tornado is about to form.
Turbulence within the cumulonimbus cloud will cause the mammatus to form.
Especially on the underside of the projecting anvil.
Their striking appearance is most visible when the sun is low in the sky and their pouches are framed by the sunlight.
