Cumulus clouds are a type of cloud that is fluffy, with a white or light gray color. These clouds are often associated with fair weather, but can also develop into larger storm clouds. They are formed by the upward movement of warm air, which causes the air to cool and condense into water droplets.
Cumulus clouds are formed through the process of convection, where warm air rises and cools as it reaches higher altitudes. As the air cools, water vapor in the air condenses into tiny water droplets, which form the cloud. The rising air currents give cumulus clouds their puffy appearance, with flat bases and rounded tops.
Cumulus clouds are often described as having a cauliflower-like appearance, with a white or light gray color. They are typically seen on sunny days, and can be found at different altitudes in the atmosphere. Cumulus clouds are known for their rapidly changing shapes, and can vary in size from small, cotton-like puffs to large, towering formations.
