What is sunset glow?

"Sunset" refers to the colorful clouds that appear on the horizon around sunset in the evening. Colorful clouds often appear on the horizon around sunrise and sunset in the morning and evening. The morning glow and sunset glow are caused by 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.

As the saying goes, "Don't go out at sunrise, but go to Wan Li Road at sunset." 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.
