Lenticular clouds are often confused with unidentified flying objects (UFOs). They form when moist air flows through a mountain or mountain range.

UFO-like clouds

The lenticular cloud forms in a place where moist air flows through the mountain. Moving air flow constitutes a large-scale standing wave sequence according to the blowing wind.
If the temperature on the top of the wave drops to the dew point, the moisture in the air condenses to form a lens cloud.On the picture is a lens cloud on the island of Tenerife, Spain, taken in June 2015.(Photo: Roberto Porto)

When the moist air mass moves down to the low zone between the two waves, the lens-like cloud can evaporate.So they appear and disappear very quickly.

People living at low altitudes or flat terrain often rarely see a lens cloud.However, they can still form here thanks to the deformed winds created by a gong.Frong is the contact surface between two different air masses with different physical properties and properties.
