Scenes of water and sky meeting one after another appear in the Gobi Desert in Turpan, Xinjiang. What caused this?

In the Gobi Desert of Turpan, Xinjiang, scenes of water and sky appear one after another. This is the result of the simultaneous effect of reflection and refraction of sunlight. Mirages are relatively rare in the local area in winter. of. 1: Xinjiang version of "mirage"

On November 27, it was reported that a very strange sight was seen in the Kumtag Desert Scenic Area in Shanshan County, Xinjiang. The originally dry and desolate Gobi Desert actually turned into a mirage. The scene of mirages that look like lakes, sand dunes, or tall buildings, where water and sky meet, appears one after another, which is very spectacular. According to the investigation conducted by my staff at the meteorological station, small puddles appeared on the desert at first, and quickly formed a lake in the next hour. Waves and water plants on the lake could still be vaguely seen, and there were also mirages. You can see the sparkling water on the lake, the water waves rolling in the wind, and the water plants floating on the lake. Moreover, this kind of mirage phenomenon in winter is relatively rare in the local area. 2: The principle of mirage

In fact, from a scientific perspective, mirage is not that magical. The cause of the formation of mirages is actually closely related to weather conditions, meteorological conditions, geographical location, geophysics, etc. To put it bluntly, a mirage is actually an optical phenomenon. When light propagates in a medium with uniform density, it will advance in a straight line with unchanged speed and direction. But when light enters another medium obliquely, its propagation direction will change, causing the light to be deflected at the junction of different media. This is the refraction of light, which is the fundamental reason for the generation of mirages. To put it simply, it is refraction. Three: The magical thing about mirages is that they are not common

Mirages often occur in coastal areas and are occasionally seen in desert areas. People can see houses, people, mountains, forests and other scenery. The essence of mirages is a Optical phenomena generally only appear in calm and windless environments, and the atmospheric structure above the ground shows an abnormal increase in temperature with height, so the mirage itself is difficult to see. So people who see mirages must be very lucky. I also hope that I can witness a mirage with my own eyes in this life.
