What do cirrus clouds portend?
Cirrocumulus: Small round cumulus clouds that look like ripples are often called "fish scale sky". Usually, the altitude is between 5 000 and 8 000 meters, which usually indicates sunny weather.
Cirrostratus: It is made of ice particles and looks like white clouds. These are the only clouds that glow around the sun or the moon. If cirrostratus expands, it means sunny weather. If cirrostratus shrinks, it means it will rain; If the sky is covered with cirrus clouds, the sky above the cirrus clouds will darken and gradually form a cirrocumulus, which indicates the coming of rain and snow.
Altocumulus: Similar to cirrocumulus, it means good weather, but it covers a wider area, and the clouds are thicker and dark white. It usually appears after heavy rain and is suspended at an altitude of 5 000~6 000 meters.
Cumulonimbus: It's a low-level Lei Yun with dark clouds. Towering clouds can reach up to 6000 meters, and the clouds with flat tops are called anvil tops. Cumulonimbus clouds often bring strong winds, heavy rains and lightning. The upper layer resembles a false cloud, and the top layer resembles a false rain cloud.
