Is it sunset glow?

Sunset is not a cloud \ r \ n \ r \ Sunset is a rosy cloud that appears at sunset. According to Rayleigh scattering law, light with shorter wavelength such as violet, blue and cyan in the solar spectrum is most easily scattered, while light with longer wavelength such as red, orange and yellow has stronger light transmission ability. So we see that the clear sky is always blue, while the light above the horizon is only yellow, orange and red with longer wavelengths. After these rays are scattered by impurities such as air molecules and water vapor, the sky there will be colorful. \ r \ n \ r \ nAs the saying goes, "Stay indoors at sunrise and go to Wan Li Road at sunset". In other words, the bright red morning glow shows that there are many water droplets in the atmosphere, which indicates that the weather is going to turn rainy. If there is a fiery red or golden sunset glow, it means that there is no cloud in the west, and the sunlight can be transmitted to form a sunset glow, which indicates that the weather will be fine. Colorful clouds sometimes appear on the horizon around sunrise and sunset. The chardonnay seen in the eastern sky around sunrise is called morning chardonnay, and the chardonnay around sunset is called sunset chardonnay. \ r \ n \ r \ nHaze is the result of sunlight passing through the thick atmosphere at 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.
