Sunset appears, will it rain the next day?

No, the appearance of sunset glow indicates that the weather will clear up. As the saying goes, "the morning glow does not go out, and the sunset glow travels thousands of miles." In other words, the bright red light in the morning 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.

Extended data

Formation principle of sunset glow:

The formation of sunset glow is due to the scattering of light by air. 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 the clear sky is always blue, and 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.
