Cumulus congestus clouds are formed when cumulus clouds rise high creating a tower like shape. When cumulus fractus clouds make their way, the moisture in these clouds evaporates in the surrounding air. Basically, water vapor starts condensing at a particular altitude, and as it rises further, it tends to drift upwards in the earths atmosphere, which gives these clouds their characteristic fluffy appearance with a flat base. Weak convective currents create shallow cloud layers because of drier, stable air above preventing continued vertical development.
Cumulus clouds are often described as puffy, cottonlike or fluffy in appearance, and have flat bases. To understand how clouds form, we need to take a step back and examine the processes of evaporation and condensation. Towering cumulonimbus clouds are typically accompanied by smaller cumulus clouds.
