Definition of cirrocumulus in US English:



  • Cloud forming a broken layer of small fleecy clouds at high altitude, usually 16,500–45,000 feet (5–13 km), typically with a rippled or granulated appearance (as in a mackerel sky).

    • ‘The breeze was soft, but bracingly cool, and the deep blue of the sky was checkered with a high cirrocumulus web, glinting golden and magenta in the glancing sunlight.’
    • ‘The cirrocumulus formation is basically the same cloud as the stratocumulus and altocumulus but at higher altitude.’
    • ‘They are similar to the higher cirrocumulus, but are larger and have dark, shadowy sides.’
    • ‘Cirrocumulus has no shading (which altocumulus usually has), and because it is so much higher, the cloudlets of cirrocumulus are much smaller than those of altocumulus.’
    • ‘The type of clouds most often found in the high level étage are cirrus, cirrocumulus and cirrostratus.’
