Colorful clouds often appear on the horizon in the morning and evening, around sunrise and sunset. 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.

Proverbs and poems

Stay indoors at sunrise and travel thousands of miles at sunset.

Sunset, infinitely beautiful, only near dusk.

The vast desert is lonely, and the Yellow River sets the yen.

Although the sun has set, the afterglow is still shining in the sky.

Formation principle

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.

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.

Although the morning glow does not go out, the evening glow goes to Wan Li Road, but there is also an old saying in Chaoshan area of Guangdong Province: "The evening glow is full of red sky, and there will be a typhoon in three days." In other words, there will be a typhoon at sunset in the next three days.

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.

Caiyun Similar to a rainbow, a light phenomenon that occurs in the morning and evening is not as regular as a rainbow, but as random as spilled paint. Like abstract painting, there is a vague beauty.

The "sunset glow" in the evening, also called "flaming clouds", is bright red in color, changeable in shape and small in cloud body. In ancient times, there was a saying that "the morning glow does not go out, and the sunset glow travels thousands of miles", because the morning glow is mostly caused by cumulonimbus clouds, which are very easy to develop into cumulonimbus clouds; Sunset clouds are mostly caused by light cumulus clouds, which will not cause precipitation. Generally, it indicates that it will continue to be sunny in a certain range in the next few days, which is conducive to travel.

morning glow

In the early morning, when the sun just comes out, or when the sun is about to set in the evening, the clouds on the horizon are often red, like fire.

Burning clouds are red clouds that appear at sunrise or sunset. Sunset clouds belong to the category of low clouds, which is one of the phenomena of atmospheric change. It often appears in summer, especially around sunset after a thunderstorm, in the west of the sky. Due to the strong evaporation on the ground and the great action of updraft in the atmosphere, the shape of fire clouds is ever-changing. The color of flame clouds is generally red. The appearance of flaming clouds indicates that the period of warm weather, abundant rainfall and flourishing biological growth is coming.
