Cirrocumulus cloud

Genus of high-altitude clouds

Cirrocumulus is one of the three main genus types of high-altitude tropospheric clouds, the other two being cirrus and cirrostratus. They usually occur at an altitude of 5 to 12 km (16,000 to 39,000 ft), however they can occur as low as 10,000 ft (3.0 km) in the arctic and weather reporting standards such as the Canadian MANOBS suggests heights of 29,000 ft (8.8 km) in summer and 26,000 ft (7.9 km) in winter. Like lower-altitude cumuliform and stratocumuliform clouds, cirrocumulus signifies convection.
