In the long term practice of production and life, people observe the changes of clouds, what weather

It is a sign of impending heavy rain or heavy rain, and through such clouds. It is also possible to judge future weather changes.

This kind of cloud indicates that the weather on the second day will be clear, and there is also a saying called fish scale spots in the sky, and the sun does not need to turn over the grain, which is talking about cirrocumulus clouds.

I think that having cirrocumulus weather means that it may rain, and then the weather will change, so you must be prepared for this.

Cirrus: A high-level wisp cloud formed by ice crystals, which is why it looks pure white, often called a horsetail cloud. They also usually mean clear weather, 5 000 9 000 meters high.

Cirrocumulus: Small round cumulus clouds, which look like ripples, are often referred to as "fish scales", usually at altitudes of 5 000 to 8 000 meters, and generally indicate clear weather.

Cirrostratus: Formed by ice particles that look like white clouds, these are the only clouds that create a halo around the sun or moon. If Cirrostratus expands, it means that the weather is clear; If the cirrostratus clouds shrink, it means that it is going to rain; If the sky is shrouded in cirrus clouds, the sky above the cirrus clouds darkens and cirrocumulus clouds gradually form, which signals the arrival of rain and snow.

Altocumulus: Similar to Cirrocumulus, it portends good weather, but it has a wider coverage, thicker clouds, and white and dark clouds. It usually occurs after a heavy rainstorm and is suspended at an altitude of 5,000 to 6,000 metres.

Cumulonimbus clouds: low-level thunderclouds with dark clouds. Tower-shaped clouds can reach heights of up to 6,000 metres, and the flat cloud layer at the top is called the anvil top. Cumulonimbus clouds often bring strong storms, thunder and lightning. The upper layer resembles a false cirrus cloud, and the top layer resembles a false rain cloud.

Cumulus clouds: Easy to identify, fluffy white clouds, like clumps of cotton wool, floating in the air. If you are separated from each other, it means that it is a beautiful sunny day, but if it grows bigger and bigger, and there are more and more fronts, it is likely to bring a sudden rainstorm.

Cumulus clouds located in the blue sky over the sea usually indicate that they are not far from land, and the height is generally not more than 2,500 metres.

Altostratus: Looks like a gray curtain when illuminated by sunlight or moonlight. If moist air approaches, the cloud disk disappears and the cloud thickens and darkens until it rains, reaching heights of 2,500 to 6,000 metres.

Nimbostratus: Low-lying dark clouds that shroud the air, meaning that there will be rain within 4 hours, usually for a few hours.

Stratocumulus: Low-lying shingle-like clouds, usually covering the entire sky. The clouds are thin and sunlight can pass through. They may bring thundershowers, but they generally disappear in the early afternoon, leaving behind a clear and bright blue sky. The height is less than 2,500 meters.

Stratus: The lowest level of clouds hangs in the sky like a thick fog, which is often mistaken for a dense mountain fog when it first appears. They are not very natural rain clouds, but they can also form misty drizzles.

If at night it is thicker and thicker, covering the early morning sky, usually it will be a clear day, the height does not exceed 2,500 meters.

1. The concept of cumuliformous clouds: Cumuliform clouds are vertically developed cloud blocks, including Cumulus pailis, Cumulus congestus and Cumulonimbus. Cumuliform clouds are mostly formed in the summer afternoon, with isolated and scattered appearances, flat bases and raised tops.

Formation conditions: (1) atmospheric convective upward movement; (2) The height reached by the convection rise is higher than the height of condensation.

2. Characteristics and observational significance of cumuliform clouds.

The appearance characteristics, base height and appearance time of the same type of cloud vary from season to season, as is the case with Cumulonimbus. In spring, due to the lack of water vapor ** and insufficient thermal conditions, the horizontal range of cumulonimbus clouds is small, there is no anvil cirrus at the top, and there is no obvious hanging ball at the bottom, but it is dark strip-like, block-like, generally does not thunder, and is easily confused with stratocumulus. In this case, it is necessary to make continuous observations and make accurate judgments based on the speed of the clouds and changes in surface meteorological elements.

Summer is the season when convection is the most vigorous, with the most cloud cover and cloud formation, and the most weather phenomena. For the cumulonimbus clouds with deep convection to the later stage, the characteristics of the bottom roller and the hanging ball are particularly obvious, and it moves fast, often accompanied by severe weather phenomena such as thunder, lightning and strong winds. At this time, it is necessary to pay attention to its development and movement, and observe it outdoors.

In autumn, the subtropical high weakened, but due to the influence of polar cold air masses and denatured air masses, there were still many showers. At this time, the power of the cumulonimbus cloud is not as strong as in summer, but its individual characteristics are still evident, often accompanied by thunderstorms and sometimes heavy precipitation.

Clouds refer to the water vapor that rises into the sky.

Colloquial explanation:

When the weather is clear and the air temperature is high, the water on the surface of the earth is evaporated into the air, and the cold air at high altitude condenses, and the large patches are connected together to form the clouds we see now.

The thinner and whiter the clouds, and the thicker and darker the clouds.

The clouds are full of water ions and are charged. The thicker the clouds, the greater the charge, and when two clouds collide, lightning and thunder will occur.

At the same time, when the water vapor in the clouds encounters a large area of cold air, the water vapor forms water droplets, and when the water droplets crystallize too much, the buoyancy can not bear it and it will fall, forming rain, snow, hail, etc.

Of course, the wind is the catalyst, and if the clouds gather quickly, and soon the white clouds turn into black clouds, or the black clouds move quickly, it must be a strong wind at high altitude, and in the same way, the surface wind speed will not be too small.

In general, professional terms can be flipped to books.
