The height of the cloud?

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.

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. The tower cloud can be as high as 6,000 meters, and the flat cloud at the top is called anvil cloud. Cumulonimbus clouds often bring strong storms and lightning. The upper layer resembles a false cirrus cloud and the top layer resembles a false rain cloud.

Cumulus: It is easy to identify, fluffy white clouds, like floc, floating in the air. If we are separated, it will mean another beautiful sunny day, but if it gets bigger and bigger and there are more and more front ends, it is likely to bring a sudden rainstorm. Cumulus clouds in the blue sky at sea usually indicate that they are not far from land, and the height is generally not more than 2500 meters.

Cirrus: a high-level bunchy cloud formed by ice crystals, which is why it looks pure white. Often called ponytail cloud. They usually mean sunny weather, 5000-9000 meters high.

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 the weather is fine; 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.

High-level cloud: It looks like a gray curtain in the sun or moonlight. If wet air approaches, the cloud disk disappears, and the clouds become thicker and darker until it rains, and the height can reach 2500 ~ 6000 meters.
