Cumulus Clouds

Cumulus clouds are fluffy, white clouds with flat bases. They are often described as looking like cotton balls or cauliflower. These clouds are formed by the upward movement of warm air and indicate fair weather. Cumulus clouds are typically found at lower altitudes and are associated with pleasant, sunny days.

Formation of Cumulus Clouds

Cumulus clouds form when warm air near the Earth's surface rises and cools as it ascends. As the air cools, the moisture in the air condenses to form water droplets, which cluster together to create the puffy appearance of cumulus clouds. The flat base of cumulus clouds is formed when the rising air reaches a stable layer of the atmosphere, causing the cloud to spread out horizontally.
