The word “cumulus” refers to a type of cloud that is characterized by its fluffy, white appearance and a heaped or piled structure. Cumulus clouds typically form in fair weather and are associated with rising air. The term can also be used in a broader sense to describe something that is heaped or amassed in a pile or cluster. In a more specific context, “cumulus” can refer to the “cumulus” layer of clouds in the atmosphere.
