Initial data
Over the Arab Emirates there is a strange anomaly – a hole that eerily frightened the locals. People, by the way, called what he saw a portal to hell.
To reassure people, scientists published a theory explaining the phenomenon. So, the ice crystals tend to disappear periodically, or they melt, or move due to external factors (they can be passing the aircraft, for example).
It should be noted that such holes can be observed away from the routes. This situation experts find it difficult to explain. Also, they can't say why the anomaly is characterized by limitations in size and has a regular geometric shape. Above we offer you to look at the "portal to hell" that is rapidly spreading users of social networks.

Original news
The mysterious ‘whirlpool hole’ appeared out of nowhere above the city of Al Ain in the Gulf State. Whilst the rest of the sky was a bed of consistent cloud, this circular phenomenon punched a clear hole into the stratosphere, allowing light to bounce down into the desert. Astronomer and meteorologist Ebrahim Al Jarwan posted a short video clip of the hole on Twitter, adding that the “rare and beautiful” sight was referred to as a 'Fallstreak hole' or 'hole punch cloud'.One user replied that it looked as if "God has thrown a stone into a lake", while others pondered whether the strange phenomenon had been caused by an extraterrestrial UFO.
But meteorologists weren't having any of it and demystified the dramatic formation with a scientific explanation.
The phenomena tend to form in mid-to-high level clouds made up of supercooled water droplets - water below 0°C but not yet frozen.
Hypotheses
Cloud (natural and man-made)
Clouds are the products of condensation of water vapor suspended in the atmosphere, visible in the sky from the surface of the earth. They consist of tiny drops of water and/or ice crystals (called cloud elements).
Events
Rocket launches (from space.skyrocket.de)
- Site: Cape Canaveral Air Force Station, Eastern Test Range, Cape Canaveral, Florida (USA) Vehicle: Delta-4M+(5,4) (upg.) Payload: WGS 10 (USA 291)
Investigation
It is quite a common formation in the clouds, periodically occurring worldwide.
This effect can be seen in cirro-Cumulus clouds — large circular gap that is called a Fallstreak. Hole in the clouds caused by falling ice crystals.
Ice crystals can form in the higher clouds or the condensation trail of the aircraft flown. Usually they are produced by the plane passing through such a cloud layer. In this case, if the air has a suitable temperature and moisture content, the falling crystals will absorb water from the air and grow.
For this to happen, the water must be so cold that freezing it needs only a suitable surface. Loss of moisture in the air increases the evaporation rate of water droplets in the cloud, and they are scattered, forming a hole.
