What are fair weather cumulus made of?

Fair weather cumulus have the appearance of floating cotton with a flat base and distinct outlines, and colors range from white to light gray. Fair weather cumulus have a lifetime of anywhere from 5-40 minutes and show only slight vertical growth, with the tops designating the limit of the rising air.

What type of clouds are puffy and white?

Cumulus: Cumulus clouds are the clouds you learned to draw at an early age and that serve as the symbol of all clouds (much like the snowflake symbolizes winter). Their tops are rounded, puffy, and a brilliant white when sunlit, while their bottoms are flat and relatively dark.

Why do cumulus clouds form at cold fronts?

Cold air is more dense than warm air, so when a warm air mass meets a cold air mass, the cold air ends up below the warm air. Cold fronts occur when heavy cold air displaces lighter warm air, pushing it upward. Cumulus clouds are the most common cloud types that are produced by cold fronts.

Where do cumulus clouds form in the atmosphere?

Cumulus clouds form in areas where the ground is very warm. The warm air on the ground speeds the evaporation of surface water. That moisture gets pulled up into the atmosphere by an uplift. The warm air carrying moisture enters cooler temperatures higher in the atmosphere.

Does a cumulus cloud make rain?

Most forms of heavy precipitation fall from cumulus clouds. The weather they bring depends on their height and size. The higher the base of a cloud is, the drier the atmosphere and the fairer the weather will be. Clouds located close to the ground mean heavy snow or rain.

Whether this appears as rain or snow will depend on the air temperature closer to ground level. Cumulonimbus clouds are known for bringing severe weather including high winds, hail, and thunderstorms. As they grow much taller than a cumulus cloud, they can occur at altitudes up to 50,000 feet.
