Cirrocumulus clouds are high-altitude clouds that form above 20,000 feet (6,000 meters), typically in the upper part of the troposphere. These clouds are made up of tiny ice crystals due to the cold temperatures at such high altitudes. They often appear as small, white, fluffy patches or rows, sometimes resembling cotton balls or a field of grains. Cirrocumulus clouds are typically seen in fair weather, but their presence can also signal that the atmosphere is unstable, and they may sometimes precede a change in weather. These clouds are often scattered across the sky in a patchy or streaky pattern, which can sometimes look like a "mackerel sky."
