Blue sky, how are white clouds formed, and what changes do white clouds in the sky?

Formation of white clouds:

1. The isolated cumuliform cloud appears to be white because the cloud layer is relatively thick, and the light is almost completely reflected on the sunny side.

2. The water on the ground absorbs heat and turns into water vapor, which rises to the upper layer of the sky vapor layer. Due to the low temperature of the upper layer of the vapor layer, the volume of water vapor decreases, the specific gravity increases, and the steam decreases.

3. Due to the high temperature below the vapor layer, it absorbs heat during the descending process, rises again and cools again, and then descends, so that the volume of the gas gradually decreases, and finally concentrates on the bottom layer of the vapor layer. A low temperature zone is formed at the bottom layer, and water vapor is concentrated in the low temperature zone, which forms a cloud.

Extended Information: The sky has clouds of various colors, some white as flocculent, some as jet black, some gray as gray, and some red and purple as they glow. Here, the thickness of the clouds determines the color, and the thickness of the various clouds we see varies greatly, with a thickness of up to 7-8 kilometers and a thin one of only a few tens of meters.

There are many types of stratiform clouds, solitary cumulinary clouds, and undulating clouds. Very thick stratiform clouds, or cumulonimbus clouds, where the light of the sun and moon is difficult to penetrate, and the clouds appear very dark; The slightly thinner stratiform and undulating clouds appear gray, especially the undulating clouds, with more grayish colors at the edges of the clouds. Very thin clouds, light is easy to pass through, especially thin clouds composed of ice crystals, the filaments appear particularly bright in the sun, with a silky luster, and even if there are such stratiform clouds in the sky, ground objects will still reflect shadows in the light of the sun and the moon.

Sometimes the clouds are so thin that they are barely visible, but as long as one or several large rings are found near the sun and moon, it can still be concluded that there are clouds, which are called "cirrostratus clouds".

The sky is blue because of the scattering, and the white clouds are white because of the water vapor.

1. The reason why the sky is blue: The scattering of sunlight by the density fluctuation of the air itself forms a blue sky. In 1910, Einstein used the then newly developed entropy (chaos.

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.
