Haze is the result of sunlight passing through the thick atmosphere around sunrise and sunset and being scattered by a large number of air molecules. When there are many impurities in the air, such as dust and water vapor, its color is more obvious. If there are clouds, they will also be dyed orange and red.

The bright red glow before and after sunrise shows that there is already a lot of water vapor in the atmosphere, and clouds have invaded this area from the west, indicating that the weather will turn to rain. The appearance of a bright red and golden sunset indicates that the weather in the upper reaches of our western region has cleared up or the clouds have split, and the sunlight can penetrate to cause the sunset glow, indicating that the rain clouds hanging over the local area are about to move eastward and the weather will clear up.
