A cumulus cloud is a cloud belonging to a class characterized
by dense individual elements in the form of puffs, mounds or
towers, with flat bases and tops that often resemble
cauliflower. They are formed in the troposphere at a lower
altitude than altocumulus, usually below 8,000 feet (2,400
metres). "Cumulus" is Latin for "heap", related to "accumulation".

They have often been described as cauliflower-like in
structure. They occur at heights of 1,640 - 19,685 feet
(500-6,000 meters) in elevation from the earth and most often
occur scattered or in dense heaped packs. They are formed
due to convection. Buoyant, upward air currents, known as
thermals rise to a height at which the moisture in the air can
condense. Though most common in warm, summer weather,
cumulus clouds can be formed at any time of year.

Cumulus clouds often form in anti-cyclonic weather but
sometimes the descending air in the anticyclone produces an
inversion layer which prevents the air rising to a height where
its moisture can condense. In these conditions cumulus clouds
do not form and the sky is cloudless.
