How clouds are formed What are the shapes of clouds

The shape of the cloud is as follows:

1. Cumulus clouds: very 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 meters.

2. Cumulonimbus clouds.

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

The top layer resembles a false rain cloud.

3. Stratocumulus.

The lower layers are covered with shingle-like clouds, which usually cover the entire sky. The clouds are thin and sunlight can pass through. They can bring thundershowers.

But it usually disappears in the early afternoon, leaving behind a clear and bright blue sky. The height is less than 2500 meters.

4. Stratus clouds: The clouds are the lowest, like a dense fog shrouded in the air, and they are often mistaken for mountain fog when they first appear. They are not very natural rain clouds, but they can also form misty drizzles.

If at night it gets thicker and thicker and covers the early morning sky, usually it will be a clear day, the height does not exceed 2500 meters.

5. Altocumulus.

Similar to Cirrocumulus clouds.

Omen weather is good, but it has wider coverage, thicker clouds, and white with darkness. It usually occurs after a rainstorm and is suspended at an altitude of 5,000-6,000 meters.

1. Cirrus clouds: The cloud body has a fibrous structure, often white, no shadow, hairy luster, mostly silky, flake-like, feather-like, hook-like, clumpy, anvil-like, etc. It is mostly composed of ice crystals with a diameter of 10-15 microns.

2. Stratus: Stratus has no structure at all, it is composed of tiny water droplets. Stratus clouds tend to have drizzle or drizzle, but not heavy rain.

3. Cumulus clouds: The top of the vertical upward development is arc-shaped or arch-shaped overlapping and convex, while the bottom is almost horizontal cloud block.

4. Nimbus clouds: The cloud body is huge like a towering mountain, the top begins to freeze, the outline is blurred, there is a fibrous structure, the bottom is very dark, and there are often rain flags and broken rain clouds.

1. The clouds in the sky can be varied and varied. Some are like a flock of little sheep, some are like a cute puppy, and some are like a ball of cotton candy. I looked up at the white clouds, as if there was a cute little dog grinning at us.

It's so cute! I love the white clouds in all their forms!

2. The clouds in the sky are really varied and changeable. Some of them are like feathers, floating gently in the air; Some are like fish scales, neatly arranged in patches; Some are like flocks, coming and going; Some are like a large quilt, covering the sky full; Others are like peaks, like rivers, like heroes, like galloping horses, ......

3. Clouds in the sky = thousands of postures and changes. Some of them resemble feathers, floating gently in the air; Some are like fish scales, neatly arranged in pieces; Others are like mountains, like rivers, like lions, like galloping horses, ......Sometimes they adorn the sky beautifully, and sometimes they cover it gloomily. Just now, it was still white clouds and the sun was shining, but for a while, it was dark clouds and heavy rain.

4. The clouds in the sky are in thousands of forms, like horses, stepping on the blue clouds, galloping in the rhythm of the earth; Sometimes they decorate the sky beautifully, sometimes they cover the sky very gloomy, sometimes like smiling faces, warming our hearts.

5. There are thousands of clouds in the sky, some of them are like elephants, drinking the clear water in the sky; Some of them are like little tigers, they are playing with each other; Others are like kittens, chasing her balls of thread. There were so many clouds in the sky, and they were free to fly and play in the air. Do you hear that, how happy they are laughing?

6. The clouds in the sky have thousands of forms, when it is sunny, the clouds are as white as snow floating in the blue sky, it is sometimes like a big horse galloping, sometimes like a fish swimming freely, sometimes like a feather floating in the sky, it is really varied, varied.

7. The clouds in the sky are in a variety of forms, floating in the sky like a charming and moving fairy wearing a light veil and floating down from the nine heavens. The sky floats like a dazzling colored satin, decorating the blue sky. A few white sails floating in the sky like a boundless sea.

As follows:

1. There are white clouds floating in the sky, like beautiful sheep on the grassland, like cotton wool floating in the sky, like cotton candy eaten by children in the playground, ever-changing and beautiful.

2. The clouds in the sky are fluttering, some are like galloping white horses, some are like meek sheep, some are like delicious marshmallows, some are like beautiful angels, and some are like flying eagles.

3. The white clouds are like a soft marshmallow floating in the air, the white clouds are like a piece of cotton wool gently floating in the air, and the white clouds are like a child's face, and they will make up an appearance.

4. The white clouds are layer by layer, like a staircase paved with noisy cotton; white with blue clouds one by one, like sails floating in the sky and sea; The white clouds are blooming one by one, like snow lotus in the open valley.

5. The clouds in the sky are in a variety of shapes. For a while, it is like a horse galloping in the vast grassland, for a while, it is like a fresh and beautiful painting, and for a while, it is like an old man carrying a bamboo basket for collecting medicine all over the world.

Large clusters of Cumulus clouds, large patches of Stratus and fibrous Cirrus.

Clouds are visible polymers floating in the air composed of small water droplets or Xiaoice crystals formed by the liquefaction of water vapor in the atmosphere when cold.

Introduction

The white and transparent cloud curtain, the sun and the moon are clearly outlined when passing through the cloud curtain, and the ground features have shadows, and there are often halos. Sometimes the structure of the clouds is so thin that it is barely visible, giving only a milky white color to the sky; Sometimes the structure of the silk strands is faintly discerning, as if it were messy silk. In the northern and western plateaus of China, there can be a small amount of snow in winter Cirrostratus clouds.

Thick cirrostratus clouds are easily mixed with thin Altostratus. For example, the sun and the moon are clearly defined, and the ground features have shadows or halos, or there are filaments of the structure of Cirrostratus; If only the position of the sun and the moon is identified, there is no shadow or halo on the ground, and it is a high-level cloud.

Reasons for the formation of the shape of the "cloud":

When the sun shines on the Earth's surface, the water evaporates to form water vapor, and once the water vapor is supersaturated, water molecules collect around the dust (condensation nuclei) in the air, and the resulting water droplets or ice crystals scatter sunlight in all directions, which gives the appearance of clouds. In addition, clouds can take on a variety of shapes, and they are divided into many types depending on the height and shape of the sky.

It can be roughly summarized into three shapes: block, wavy and layered

1. Clouds like cotton or mountain peaks are often isolated and scattered in the blue sky, and such clouds are called lumpy clouds. Usually massive clouds are formed by the upward movement of air, or the movement of air over a small area.

2. Some clouds look like undulating waves, we call them undulating clouds. This is usually caused by an uneven distribution of hot and cold air in a certain layer of the sky, where the air is rising at the peak and falling at the trough.

3. The clouds that fill the sky are stratiform clouds, which tend to be thick and wide, and can cover a large area. Stratiform clouds appear after hot air meets cold air.

Because some clouds are formed by small water droplets, and some clouds are formed by ice crystals, and the shape of the ice crystals is also different. For example, Cumulus is formed by a large number of small water droplets, and it looks like a large mass of cotton wool. Cirrus clouds, on the other hand, form in the sky very high and are made up of tiny ice crystals, so they look like many filaments.
