What are the characteristics of clouds in the four seasons? Do they have their own names?

Include stratocumulus, stratocumulus, nimbostratus, cumulus and cumulonimbus, among which stratocumulus, stratocumulus and nimbostratus are composed of water droplets, and the height of the cloud bottom is usually below 2500m. Most low clouds are likely to rain, and there is often continuous rain and snow in nimbostratus. Cumulonimbus clouds and cumulonimbus clouds are composed of water droplets, supercooled water droplets and ice crystals. The height of the cloud bottom is usually below 2500 meters, but the cloud top is very high. Cumulonimbus clouds often have thunderstorms, sometimes accompanied by strong winds and hail.

stratocumulus

Clouds are generally large, with great differences in thickness or shape, often gray or grayish white, and loose structure. Thin clouds can distinguish the position of the sun and the moon; Thick clouds are darker. Sometimes scattered, mostly in groups, rows and waves, neatly arranged in one or two directions. Stratocumulus can be divided into five categories:

Translucent stratocumulus

The clouds are thin and gray, arranged neatly, and the blue sky can be seen at the gap. Even if there is no gap, the edge of the cloud is brighter.

Opaque stratocumulus

Thick clouds; Dark gray, seamless between clouds, often layered, all day, with obvious ups and downs at the bottom.

stratocumulus

The size of the cloud block is not-,but gray or dark gray, and the top has the characteristics of cumulus, which is flattened by descending cumulus or cumulonimbus.

Lentiform stratocumulus

Clouds are flat and are usually formed directly by the rising of hot air scattered on the ground in the evening.

stratocumulus

The top of the cloud is protruding, and the bottom of the cloud is connected with a horizontal line, similar to a castle in the distance.

stratus

Clouds are layered, gray and foggy, but they are not connected with the ground and often cover the mountainside. Stratospheric clouds can be divided into two categories:

stratus

Clouds are layered, gray and foggy, but they are not connected with the ground and often cover the mountainside.

Fractal stratus

Broken stratocumulus fragments formed by stratocumulus splitting or fog lifting.

Cloud

Clouds are evenly layered, covering the whole day, completely covering the sun and the moon, and are dark gray. The cloud bottom is often accompanied by broken rain clouds, which reduces the continuous rain and snow. Nimbostratus can be divided into two categories:

Cloud

Clouds are evenly layered, covering the whole day, completely covering the sun and the moon, and are dark gray. The cloud bottom is often accompanied by broken rain clouds, which reduces the continuous rain and snow.

Fractal nimbus, fn

Clouds are low and broken, with changeable shapes and gray or dark gray. They often appear under nimbostratus, cumulonimbus clouds and sheltered high-level clouds, and are formed by evaporation of precipitation and condensation of air humidity.

cumulus

The individual is obvious, the bottom is flat, the top is convex, and the clouds are incoherent. The light receiving part of the cloud is white and bright, and the bottom of the cloud is dark. Cumulus clouds can be divided into three categories:

Short cumulus

The individual is small, the outline is clear, the bottom is flat, the top is raised in an arc shape, like steamed bread, and the thickness is less than the horizontal width.

cumulus congestus

The individual is tall, with clear outline, flat and dark bottom, and the curved top overlaps like cauliflower, and the thickness exceeds the horizontal width.

Fractal cumulus

The individual is small, the outline is incomplete and the shape is changeable. Most of them are white fragments, broken or primary cumulus clouds.

cumulonimbus

The clouds are thick and thick, and they are as big as towering mountains. The top begins to freeze, the outline is vague, there is a fiber structure, the bottom is very dark, and there are often rain banners and broken rain clouds. Cumulonimbus clouds can be divided into two categories:

cumulonimbus

The cloud top began to freeze, the arcs overlapped, and the outline was blurred, but it had not spread outward.

Capillary cumulonimbus

The top of the cloud has a white filamentous fiber structure, which expands into a horsehair or anvil shape, and the bottom of the cloud is dark and chaotic.

Medium cloud species

altostratus

Clouds are evenly layered, grayish white or gray, covering the whole day. High-level clouds can be divided into two categories:

Translucent stratospheric cloud

Clouds are thin, uniform in thickness and grayish white, and the outlines of the sun and the moon are blurred, like a layer of ground glass.

Opaque upper layer cloud

Clouds are thick and gray, and stripes of light and dark can be seen at the bottom. The sun and the moon are covered, and you can't see the outline.

altocumulus clouds

The clouds are small and well-defined. Thin clouds are white and can see the outline of the sun and the moon; Thick clouds and gray, the outline of the sun and the moon is indisputable. Flat, tile-shaped, fish-scale or wavy dense cloud bands. Arrange in groups, rows and waves in one or two directions. Cumulus clouds can be divided into six categories:

Translucent cumulus clouds

The clouds are thin, the individuals are arranged neatly, and the blue sky can be seen in the cracks of the clouds; Even if there is no gap, the thin part of the cloud is brighter.

Opaque cumulus clouds

Clouds are thick and densely arranged, there is no gap between them, and the position of the sun and the moon is also unclear.

Lenticular altocumulus

Clouds are white, thick in the middle, thin in the edge, well-defined, isolated and scattered, shaped like pods or lemons.

Castellanus cumulus, ac casting

The bottom of the cloud block is flat, and several small cloud towers protrude from the top, similar to the castle in the distance.

Ac flo opaque cumulus clouds

The edge of the cloud is broken, much like cotton wool.

cumulonimbus

Clouds vary in size, are grayish white, and have a slight cumulonimbus appearance, which is formed by falling cumulonimbus clouds or expansion of cumulonimbus clouds.

High cloud species

Including cirrus, cirrostratus and cirrocumulus, are all composed of small ice crystals, and the height of the cloud bottom is usually above 5,000m. Generally, it doesn't rain on high clouds, but it occasionally snows in cirrostratus and Cirrus in the north in winter.

cirrus

The clouds are fibrous, white, shadowless and shiny, yellow or red before sunrise and after sunset, and gray when the clouds are thick. Cirrus clouds are divided into four categories:

ci fil

Clouds are scattered and the fiber structure is clear, such as tangled silk, feathers and tails.

Cirrus spinosus

Clouds are dense and gather into sheets.

cirrus uncinus

Clouds are arranged in parallel, with small hooks at the top to form small balls, similar to commas.

Pseudosclerosis

The ice crystals at the top of cumulonimbus clouds are large and dense, often anvil-shaped.

Clouds in the cirrostratus are all layered, transparent or milky white. Through the clouds, the outlines of the sun and the moon can be clearly seen, and objects on the ground are blocked, which often makes people dizzy. Cirrostratus can be divided into two categories: cirrostratus.

The cloud curtain is thin and uniform, and no obvious structure can be seen.

cs fil

The thickness of the cloud curtain is uneven and the filamentary fiber structure is obvious. Cirrocumulus is very small, with white scales and flakes, often in rows or groups, arranged neatly, like small ripples caused by a breeze blowing over the water. Convolution flowers have only 1 categories.

In addition, each kind of cloud has its particularity, but it is not static. Under certain conditions, this cloud can be transformed into that cloud, and that cloud can be transformed into another cloud. For example, light cumulus clouds can develop into thick cumulus clouds and then into cumulonimbus clouds; The top of the cumulonimbus is detached and becomes a pseudo cumulonimbus or cumulonimbus; Cirrocumulus descended to the upper clouds; The lowering of high-altitude clouds will turn into nimbostratus.
