For thousands of years, the working people in our country have summed up the rich experience of "knowing the sky by observing the clouds" according to the changes in the shape, direction, moving speed, thickness and color of clouds in production practice, and compiled these experiences into proverbs.

1, kareem abdul-jabbar, it is raining:

Hook cloud is called hook cloud in meteorology, which generally appears in front of warm front and low pressure. The appearance of hook clouds indicates that a warm front or low pressure is coming, which is a precursor to rain. But after rain or winter, there will be sunny days or frost, so there is a proverb that "the hook cloud dissipates, the sunny day is dry" and "the winter hook cloud dries up"

2, battery cloud, it's raining:

Fort cloud refers to fort-shaped altocumulus cloud or fort-shaped stratocumulus cloud, which appears in front of the trough with low pressure, indicating that the air is unstable, and thunderstorms usually come every 8- 10 hours.

3, clouds, rain drops:

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 "the sky will change against the wind."

4, Jiang pig crossing the river, heavy rain:

The river pig refers to the broken rain clouds falling in 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 will be blown to cloudless places by strong winds on sunny days, and at night, clouds like river pigs will be seen floating across the "Galaxy", which is also a precursor to rain.

5. Clouds are heading east, blowing gusts; Yunxi, wearing hemp fiber:

The cloud referred to here is the low cloud in the low pressure area. The low pressure is from west to east (in fact, it often moves from southwest to northeast). The cloud goes west, indicating that this place is in front of the low pressure, because it will rain locally; The cloud is moving eastward, indicating that the low pressure has moved past the local area, and the local area is behind the low pressure. The weather is going to clear up, and a strong wind often blows before it clears up.

6. Gray cloth hangs in the sky, and it rains continuously: Gray cloth cloud refers to nimbostratus, which is mostly formed by thickening and metamorphosing of high-level clouds, with a large and thick range and sufficient water vapor in the clouds, which often produces continuous precipitation.

7. the cloud goes east and the car picks up; The clouds go south and the water rises; Clouds to the west, covered with hemp fiber; Clouds heading north are conducive to drying wheat;

According to the moving direction of the cloud, it is predicted that if the cloud moves eastward and northward, the weather will be fine. The clouds move west and south, which indicates that it will rain. The moving direction of a cloud usually indicates the wind direction at its height. This proverb describes the distribution of clouds in different parts of low pressure. Suitable for low-altitude fast-moving clouds that are densely covered all day.

8, cotton cloud, rain is coming:

Cotton clouds refer to flocculent cumulus clouds. The appearance of this cloud shows 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 there will be thunderstorms.

9, northwest day unlock, Ming Sun:

It refers to a rainy day, and the clouds in the northwest direction split to reveal a blue sky, which is called "opening the sky". This shows that the local area is already at the back of the rainy weather system. As the rainfall system moves eastward, the local rainfall will stop and the weather will improve.

10, the dark clouds meet the sunset, not today but tomorrow;

When the sun goes down, a wall-like dark cloud rises below the western horizon to catch the sun, indicating that the dark cloud moves eastward, and the rainy weather in the west is moving and it is going to rain. Generally speaking, if there are clouds, it will rain that night; If you catch the high clouds, it will rain the next day. However, if the dark clouds in the west are lumpy or discontinuous, or some areas are cloudy, it is not a sign of rain in the future.
