Light refraction is an explanation of the phenomenon of city illusion on the sea

Take the illusion example in the desert. The air is heated up, and therefore it is much diluted. The upper air layer is heated less, so it is denser. The air density in both layers adjacent to each other in this case is no longer uniform. So in such conditions, somewhere in the horizon, the front of the transport team appears a ghost, and in fact, it is a reflection of the sky in the mirror of the air layer below. In essence, it is just a direct reflection of the objects in the strange air mirror that seem to cover the ground.
