A large sponge cloud appeared in the sky in Nanjing, Jiangsu Province. How are sponge clouds formed?

10, 12 In the morning, the sky in Nanjing caught fire. Because there is a large sponge cloud in the sky in Nanjing, which is very beautiful, the sky in Nanjing has also occupied a place in the circle of friends. What is the reason? This is because Nanjing has sponge clouds, clear blue sky and some big and thin clouds. It looks very good.

In fact, the professional name of sponge cloud is Altocumulus translucent cloud. This kind of cloud is formed because the density flow of cold air causes the fluctuation of the atmosphere, so this kind of performance is formed, which is also called sponge cloud.

Clouds are formed for many reasons. In fact, it is mainly due to the fact that the air rises upward and the external air pressure decreases with the height, so the air volume gradually expands and consumes heat after expansion, so when it reaches a certain limit, clouds are formed.

When the air pressure reaches a certain level, it will condense into small water droplets. These small water droplets are called cloud droplets in the cloud, with an average radius of only a few microns, but their density is very high and their descending speed is very small, so they can be suspended in the air and become clouds. ?

Clouds in nature are constantly changing and have many shapes. Different shapes of clouds are mainly caused by different forms of air ascending motion. And allow small water droplets to form, some clouds are formed by ice crystals, so there are not many reasons for the formation, resulting in different shapes of clouds.

When the sun shines on the ground, water is vaporized to form water vapor, and saturated water molecules will gather in the air and gradually disperse to various places, thus forming clouds. The formation of clouds has different shapes, and because different heights also have different shapes, the shapes of clouds are also diverse.

Clouds have various shapes, so this sponge cloud is also a shape of this cloud. The clouds under the blue sky are very beautiful, so many people like to watch them. If you see a beautiful cloud, take a picture of it and record it.
