What kind of weather does the fish scale cloud represent?

Like fish scale cloud, "fish scale cloud" is technically called translucent cumulus cloud. Before the arrival of cold air, the clouds gradually depressed and thickened, because the ichthyosis cloud is a translucent cumulus cloud. Semi-transparent cumulus clouds, like white clouds in the shape of fish scales, are a kind of cloud layer when strong cold air comes, which indicates the recent unstable weather conditions. Clouds in semi-transparent cumulus clouds are thin and white, often arranged neatly in one or two directions, and there are obvious gaps between clouds. Even if there is no gap, the edge of the cloud is bright, the upper airflow is unstable, forming a "fish scale cloud", and then it often rains.
