Cumulus clouds are a type of cloud that is fluffy, white, and often described as having a "cotton-like" appearance. They are generally associated with fair weather, but can also develop into larger storm clouds under the right conditions.

Formation

Cumulus clouds form as a result of convection, which occurs when warm air rises and cools as it ascends. As the air cools, water vapor in the air condenses to form water droplets, which collect to create the puffy, billowy appearance of cumulus clouds.

Characteristics

Fluffy and white in appearance
Usually have flat bases and rounded tops
Can range in size from small, isolated clouds to large, towering formations
Often indicate fair weather, but can develop into cumulonimbus clouds, which are associated with thunderstorms
