Does the morning glow mean rain and the evening glow mean sunny weather?
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.
Extended data
Meteorological reasons
When sunlight enters the atmosphere, it will scatter when it meets atmospheric molecules and particles suspended in the atmosphere. These atmospheric molecules and particles themselves do not emit light, but because they scatter sunlight, each atmospheric molecule forms a scattered light source.
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.
