What kind of weather do the shapes and names of various clouds imply?

1. Hook cloud refers to hook cirrus cloud. Behind this cloud, there are often fronts (especially warm fronts), low pressure or low pressure troughs moving, which indicates that rain is coming;

2. Battery cloud refers to fort-shaped altocumulus cloud or fort-shaped stratocumulus cloud, which mostly appears in front of the trough of low pressure, indicating that the air is unstable. Generally, there are thunderstorms in 8- 10 hours.

3. Cloud-to-cloud means that the moving directions of the upper and lower clouds are inconsistent, that is to say, the height and wind direction of the clouds are inconsistent, which often occurs near the front or low pressure, so it indicates rain, and sometimes the wind direction of the clouds is opposite to the ground, so there is a saying that "it is necessary to change against the wind".

4. The river pig refers to the broken rain clouds under nimbostratus. The appearance of this cloud indicates that there is a lot of water vapor in nimbostratus, and heavy rain is coming. Sometimes broken rain clouds are blown to sunny places by strong winds, and it is also a precursor to rain to see river pig-like clouds floating across the "Milky Way" at night.

5. Cotton clouds refer to flocculent cumulus clouds. The appearance of such clouds indicates that the middle atmosphere is very unstable. If there is enough water vapor in the air and there is upward movement, cumulonimbus clouds will form and thunderstorms will come.

Extended data color clouds: burning clouds

Yang 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.

In cloudy morning or evening, the air layer through which sunlight passes is thicker than that at noon. Among them, yellow, green, cyan, blue and purple are exhausted when they "walk" in the air not far away. Only red and orange light can protrude through the air layer and "dye" the horizon into red, forming a fiery red cloud.

In summer, especially at sunset after a thunderstorm, flaming clouds often appear in the west of the sky. The color of flame clouds is generally red, and the appearance of flame clouds indicates that the period of warm weather, abundant rainfall, lush biological growth and prosperity is coming.
