What are the answers to the shape change, location, thickness, weather and cumulonimbus of cirrocumulus, Cumulus, Altocumulus, cirrostratus, nimbostratus and Cumulonimbus? Urgent! !

The height of the cloud bottom from the ground is often below 2000 meters, which belongs to the low cloud family. Clouds are evenly layered, gray or grayish white, like fog, but not grounded, often covering mountains and tall buildings. It is mainly composed of small water droplets and is a kind of water cloud. Stratospheric clouds in Mao Mao sometimes rain and light snow in winter. Clouds don't last long, maybe a few hours. When the stratocumulus is blown away by the wind or tends to disappear, it is often divided into irregular fragments, which are called stratocumulus (gray or grayish white, and will clear up when it appears).

Stratus clouds are composed of water droplets or supercooled water droplets with a diameter of 5-30 microns. Stratospheric clouds are generally 400-500 meters thick.

Stratosphere clouds are formed under the condition of stable atmosphere due to strong radiation cooling or turbulent mixing at night, water vapor condensation or fog lifting. Stratocumulus often rises gradually after the sun rises, the stable layer is destroyed and the stratocumulus gradually dissipates.

Cirrus is a kind of high cloud, the highest cloud in the troposphere, with an average height of more than 6000 meters. Therefore, before the sun rises to the horizon in the morning or after sunset in the evening, the light will shine on this cirrus cloud hanging high in the air without cloud shadow, and it will show beautiful red or orange light after scattering, which is very common in the clear sky in summer.

Cirrus clouds mostly appear in the form of ice crystals, and clouds are white. Because it contains ice crystals, it looks more transparent and brighter, and the clouds in the blue sky will be cleaner and silky. Cirrus clouds are usually not thick, thin and scattered, showing a little fibrous clouds, such as feathers, hair, messy silk, or ponytails, with many postures, which is quite interesting.

Stratocumulus Sc

The height of the cloud bottom from the ground is often below 2000 meters, which belongs to the low cloud family. It is a cloud layer or scattered piece composed of flaky, massive or striped clouds. Sometimes it is wavy or undulating, just like the waves of the sea. Stratocumulus is a large water cloud with loose structure, which is mostly composed of small water droplets. It is grayish white or gray. Where the clouds are thin, the position of the sun can be recognized. Stratocumulus can be divided into translucent stratocumulus, shadow stratocumulus, cumulus stratocumulus, fort stratocumulus, bean stratocumulus and so on.

Stratocumulus clouds are generally very large, with great differences in thickness and shape, some in strips, some in blocks and some in groups. It is usually grayish white or gray. Loose and thin clouds can tell the position of the sun, while thick clouds are darker. Clouds are often arranged in groups, rows or waves.

Stratocumulus clouds consist of water droplets with a diameter of 5-40 microns. Stratocumulus in winter may also be composed of ice crystals and snowflakes. In most cases, stratocumulus is formed by the condensation of water vapor due to the mixing of air fluctuation and turbulence. Sometimes it is formed by intense radiation cooling. Thin stratocumulus generally indicates stable weather, but the stratocumulus gradually thickens and even merges into layers, indicating that the weather will change. Low-thick stratocumulus often produces precipitation, but it is unlikely to form a large-scale precipitation, because stratocumulus clouds are thin and weak in upward movement, and the possible precipitation is Mao Mao rain and sporadic light rain. Its existence affects the daily temperature change, that is, it reduces the sunshine during the day and hinders the diffusion of cold air at night, so it forms cool and humid weather.

In marine environment, the cloud bottom of stratocumulus is 150-600 meters from the ground, and the height of cloud bottom is about 600- 1500 meters behind the cold front and near the lake area. In other areas, especially the height of stratocumulus formed by cumulus diffusion can reach 900-2000 meters. The thickness of stratocumulus is usually between several hundred meters and two thousand meters. Stratocumulus is found all over the world, especially in cool seas and coastal areas, but it is rare in dry areas.

cirrocumulus

(cirrocumulus Cc)

Cirrocumulus is a cloud sheet or cloud layer composed of small-scale or spherical clouds, which are usually arranged in rows or groups, much like small ripples caused by a breeze blowing over the water. White without shadow, silky luster.

Cirrocumulus is about 5,500 meters high. Clouds are very small, white and shadowless. They are in the form of white waves, spheres or fine scales, often arranged in rows and groups, much like small ripples formed by breeze blowing on the water. I often see cirrostratus or cirrus clouds. Most of them appear before the changeable weather. Cirrocumulus is usually formed by fluctuations caused by stratification instability at high altitude.

If the sky is dominated by cirrocumulus and connected with Cirrus and cirrostratus, the development of the system generally indicates that there will be a weather system affecting the station, and there will often be stormy weather. The agricultural proverb "It's a fish scale day, but it's windy even if it doesn't rain" refers to this situation.

Cirrocumulus can be evolved from cirrus and cirrostratus. Sometimes cumulus clouds can evolve into cirrocumulus.

At the edge of the whole layer of cumulus clouds, sometimes there are small cumulus clouds, which are quite similar in shape to cirrocumulus, but don't mistake them for cirrocumulus. Only those who meet one or more of the following conditions can be considered as cirrocumulus.

(1) and cirrus or cirrostratus has obvious connection.

② It evolved from cirrus or cirrostratus.

③ It does have the silky and silky characteristics of cirrus clouds.

Cumulus (cumulus)

Cumulus clouds are composed of water droplets, but sometimes accompanied by ice crystals, which are mainly condensed by water vapor caused by air convection, rising and cooling. Therefore, the shape characteristics of cumulus clouds are closely related to the characteristics of air convection. A mass of air rises. At the beginning, the horizontal distribution of water vapor content and temperature is basically uniform, so the height of water vapor condensation is consistent. Therefore, the bottom of cumulus clouds is horizontal. In the formation stage, the updraft is strongest in the center of the cloud top, weaker around it, and flows downward outside the cloud, resulting in a dome-shaped upward bulge at the top of cumulus with obvious outline.

Cumulus clouds are mainly formed during the day, because sunlight heats the air, and in turn, the ground heats the air. Cumulus clouds can also form at the top of the mountain during the day, because the hillside heats up faster than the valley bottom. This unstable heating forms convection in motion. Cumulus clouds are sometimes formed when a cold front comes or before it. Because in the front area, the air is forced to rise.

The height of cumulus bottom is generally 600- 1200m in wet area and 3000m in dry area. The bottom of cumulus clouds is close to the ground in the morning and will rise in the afternoon.
