Will it rain in the burning clouds?

The folk proverb "get up early and don't go out, travel thousands of miles at night" means that if there is a flame cloud in the morning, the weather may get worse; Appear at night, the next day must be a sunny day.

It usually appears in the eastern sky at sunrise and on the western horizon at sunset. The appearance of fiery red clouds around sunrise indicates that there is already a lot of water vapor in the atmosphere, and the clouds have begun to invade this area from the west, indicating that the weather is going to turn rainy.

A fiery red cloud appeared in the evening, indicating that the weather in the upper reaches of our west has turned fine or the cloud has split, and the sunlight can penetrate to form a sunset glow, indicating that the rain clouds hanging over the local area are about to move eastward and the weather will turn fine.

Formation mechanism:

When the sun just comes out or is about to set, the clouds on the horizon are often red, like burning. This kind of red cloud is called sunrise and sunset, which is vividly called "flaming red cloud".

Then, the sun is a mixture of red, orange, yellow, green, cyan, blue and purple. Of these kinds of light, red light has the greatest ability to pass through the air layer, followed by orange, yellow and green light, and cyan, blue and violet light are the worst.

When the weather is clear, there are few raindrops hanging in the air. Almost all the red, orange, yellow and green lights pass through, and only blue, blue and purple light are blocked. Among these lights, blue light reflects the most, so the whole sky is "dyed" blue.
