What kinds of clouds are there in the sky?

Cloud is a kind of visible polymer floating in the air, which is composed of water droplets or condensed ice crystals formed by the liquefaction of water vapor in the atmosphere when it is cold. Clouds scatter sunlight in all directions, thus creating the appearance of clouds. Cloud is one of the most important links in the earth's water cycle.

Clouds absorb heat from the ground and reflect it back to the ground, which helps to keep the earth warm; At the same time, it also reflects sunlight back into space to cool down. Which effect is dominant depends on the shape and position of the cloud, so the movement of the cloud has a great influence on the earth's climate.

Classification of clouds

As far as morphological structure is concerned, clouds can be roughly divided into three categories, namely, cumulus clouds, stratus clouds and fibrous cirrus clouds.

The classification of clouds was first proposed by French naturalist Lamarck in 180 1 year. During the period of 1929, according to their shapes and sources, the international meteorological organization divided clouds into ten cloud genera: cirrus, cirrostratus, cirrocumulus, stratocumulus, stratocumulus, nimbostratus, cumulonimbus and cumulonimbus, and divided them into three cloud systems: high cloud system, middle cloud system and low cloud system according to the height of cloud base (suitable for mid-latitude areas).

In China, it is usually divided into three families and ten genera, and then subdivided into 29 categories. Cumulonimbus Cumulonimbus is separated from the low cloud family in the world, and is called the straight cloud family, which is usually divided into four families and ten genera.

See the weather from the clouds.

The generation and dissipation of clouds are essentially related to water vapor and atmospheric movement, and play an extremely important role in weather phenomena such as rain, snow, ice and hail. According to the change of cloud shape, moving direction, moving speed, thickness and color, you can know the weather by looking at the cloud. According to long-term observation and practice, the working people in our country have summed up many proverbs in agricultural production.

Different kinds of clouds represent different weather conditions, so I won't expand them in detail here. The direction and speed of cloud movement are related to wind direction and wind speed. The thickness of the cloud determines the color. The thickness of various clouds we see varies greatly, from more than 5 kilometers thick to less than 100 meters thin.

At present, the weather forecast is to combine satellite cloud images with local factors such as air pressure, temperature, wind direction and wind speed, and then input these parameters into the meteorological model, so that the weather situation in the next few days can be predicted.
