Cirrocumulus undulatus is a variety of cirrocumulus cloud. The name cirrocumulus undulatus is derived from Latin, meaning "diversified as with waves".[1] They have a rippled appearance due to wind shear and usually cover only a small portion of the sky. They appear in bands as small patches or layers. Occasionally, they comprise two or more wave forms superposed upon one another.[2] The individual cloudlets can either be circular or elongated in the direction of the rows.[3]
