March 8th the recorded arch-shaped cloud was widely discussed in social networks when the National Weather Service was exposed. Some people do not believe that clouds can be in this form.
First of all, it's a spacecraft. Secondly, as soon as the similar thing happens, experts are trying to convince us that this is a very rare natural phenomenon, said one internautist, who was angry at the situation.
The horseshoe on my back. I know when I see the aliens. If you let me go to my safe bunker, wrote another.
However, worrying or frightened, Internet users can lose sight of the fact that this phenomenon is completely natural. It's called the horseshoe cloud.
At least meteorologists explain this.
The horseshoe clouds are incredibly rare. It's a vortex. This requires that a stronger wind be blown up at high altitudes, and a thermal shock from the ground up. When the cloud is captured by such a warm air stream, it spins like an inverted horseshoe. As he rises to a stronger wind zone, he turns around - this twist helps him form the shape. The conditions must be quite ideal, so such clouds are very rare.
