What weather proverb does the fish scale cloud represent?

The weather proverb represented by fish scale cloud is fish scale day, and there is wind without rain.

Ichthyoid clouds are actually translucent cumulus clouds. Generally speaking, in translucent cumulus clouds, before the arrival of cold air, the clouds gradually thicken and distribute in layers. When thick clouds "squeeze" each other, they will appear fish-scale clouds. Meteorologists say that this scale cloud will become a rain cloud when it accumulates to a certain extent. The meteorological proverb vividly says, "the wind jumps even if it doesn't rain."

The change of clouds in the sky is a very important sign to predict the weather change. The proverb "Fish-scale sky, even if it doesn't rain, the wind will jump" means that there are fish-scale clouds in the sky, which means it will change. This is a sign of cloudy days. It's going to rain soon, even if it doesn't rain, there will be a strong wind. This weather proverb summarized by people is actually based on science. The so-called fish scale cloud is cirrocumulus, and cirrocumulus usually forms a rain layer, which eventually leads to rain.

Characteristics of fish scale cloud

The characteristic of translucent cumulus clouds is that the clouds are at a relatively high height, thin and white, and often arranged neatly in one or two directions. There is an obvious gap between clouds. Even if there is no gap, the edge of the cloud is bright, and the position of the sun and the moon can be distinguished. For wave clouds, clouds are well-defined, usually oblate, tiled, fish-scale or watery dense clouds.

Fish scale clouds are generally arranged in groups, rows and waves. The apparent width angle of most clouds is 1 to 5 degrees. Sometimes it appears at two or more heights. Thin clouds are white and thick clouds are dark gray. On the thin cumulus clouds, there are often rainbow colors around the sun and the moon, or Chinese rings with red outside and blue inside.
