Altocumulus clouds are a type of middle-level cloud that typically forms between 6,500 and 20,000 feet (2,000 to 6,000 meters) above the ground. They are usually white or gray and appear as rounded or flattened masses, often with a wavy or banded appearance.
Altocumulus clouds are composed of water droplets and can be found in a variety of shapes, such as rolls, bands, and ripples. They often appear in groups or layers and can cover large portions of the sky.
Altocumulus clouds can be a sign of a change in weather conditions. If they increase in size and become thicker, they may indicate that a storm is approaching. On the other hand, if they decrease in size or dissipate, it may indicate that the weather will remain fair.
Altocumulus clouds are not typically associated with precipitation, but they can sometimes produce light rain or snow. They are often seen in the morning or evening, but can also be present throughout the day.
