Relating to, resembling, or having the nature of a cumulus cloud; characterized by being piled up or accumulated.
From Latin 'cumulus' (heap) + English '-ous' (full of, having). This anglicized adjective developed from meteorological terminology to describe cloud-like or heap-like qualities in English.
Cumulous captures something poetic—it can describe not just clouds but any white, fluffy, piled-up thing, from cotton candy to freshly fallen snow drifts.
