CUMULUS. Classified as heaped cloud, are puffy clouds that sometimes look like pieces of floating cotton. Are detached, individual, cauliflower-shaped clouds usually spotted in fair weather conditions.

A developed cumulus cloud is generally dense, with sharp outlines. As it continues to develop vertically, a cumulus cloud forms mounds, domes, or towers, of which the upper parts often resemble the head of a cauliflower. The sunlit parts of cumulus clouds are brilliant white, but their bases are relatively dark.
