What kind of clouds are fish scales?

Scale clouds are called "translucent cumulus clouds" in meteorology. Generally speaking, before the arrival of cold air, the clouds are gradually depressed, thickened and distributed in layers. When thick clouds squeeze each other, they will gradually appear as fish-scale clouds, which are fish-scale clouds. Most of these clouds appear in autumn, especially when the air is crisp in autumn.

According to the experience of observing the weather through the ages, the appearance of fish scale clouds generally indicates that the weather conditions have changed recently, and there may be signs of short-term rain. Because the fish scale cloud is about the weather, there is a folk saying that "there is a fish scale cloud in the sky, and there will be a wind jump without rain."

Extended data

The formation of various clouds is mainly caused by different forms of air ascending motion. Common cumulus clouds are light cumulus clouds, dense cumulus clouds and cumulonimbus clouds. They are clouds at different stages of development, and they are mainly formed by the upward movement caused by uneven heating of ground air.

Pale cumulus clouds are flat at the bottom and convex at the top; Cumulus clouds are tall and bloated, like cauliflower; The top of cumulonimbus cloud will spread horizontally, which is called anvil cloud. Cumulonimbus clouds have strong diurnal variation characteristics and can be directly used to judge weather changes.

Stratiform clouds are uniform curtain clouds, including cirrostratus, upper clouds and nimbostratus. This cloud is mainly formed when cold air meets warm air, and warm air crawls slowly along the cold air slope. At the front end of the slope, there is a thin layer of cirrostratus; In the middle is a slightly thick high-level cloud, and finally is a very thick nimbostratus.

Wave clouds are wave cloud, including cirrocumulus, altocumulus and stratocumulus. It is produced by various upward movements of air? Wave clouds are sometimes like tiles and sometimes like fish scales, indicating different weather conditions. In addition, there are some special clouds, such as fort clouds, flocculent clouds, suspended spherical clouds, lenticular clouds and so on.
