What do you mean by cloudy weather?

Wave cloud weather means it will get cold. Corrugated stratocumulus is a low-altitude, wavy thick cloud, which usually appears before strong cold air passes through the border, indicating that the weather will change greatly. In fact, this is called "ribs cloud", which is not only vivid, but also looks delicious.

Wave cloud is a great wonder of nature, which refers to a kind of cloud that can form a miniature wave peak. When this cloud structure extends down to the island, it is like a ripple left by a ship crossing the water surface, extending for hundreds of kilometers, and finally mixing with the cumulus edge in the north.
