Incredible UFO-like cloud forms leaving onlookers in shock

The cloud hung in the sky for around an hour

Onlookers have been left stunned after a bizarre UFO-like cloud formed in the sky over a city in Turkey. The cloud formed over the city of Bursa on Thursday at sunrise, and remained intact for around an hour. It had an almost circular shape and created the illusion of having a large hole in the middle. The sunrise helped give it an eerie orange colour as well, adding to the spectacle. https://twitter.com/aktas_hafize/status/1615949735516332032 The wave-like pattern is known as a lenticular cloud. These are usually found at heights of between 2,000 and 5,000 metres. They form when the air is stable and winds blow in from hills and mountains from a similar direction through the troposphere, the lowest region of the Earth's atmosphere. Bursa lies at the base of a mountain range, making the incredible cloud formation more likely. https://www.instagram.com/p/CnrKnSjIcJq/ Explaining the phenomenon, Deborah Byrd of earth.sky.org said: "These lens-shaped clouds typically form where stable moist air flows over a mountain or a range of mountains.
