/ˌsɪɹə(ʊ)ˈkjuːmjʊləs/ · noun
(meteorology, physics) A principal high-level cloud type appearing as a thin, white patch of cloud without shadows, composed of very small droplets in the form of grains or ripples. The elements may be merged or separate, and more or less regularly arranged; they subtend an angle of less than 1° when observed at an angle of more than 30° above the horizon. Holes or rifts often occur in a sheet of cirrocumulus..
[page 99] Cirro-cumulus. […] Small, well defined roundish masses, in close horizontal arrangement. […] [page 102] The cirro-cumulus is formed from a cirrus, or from a number of small separate cirri, by the fibres collapsing as it were, and passing into small roundish masses, in which the texture of the cirrus is no longer discernible, although they still retain somewhat of the same relative arrangement.
Use cirrocumulus when its meaning, tone and grammar fit the full sentence. A synonym is not always a direct replacement.
