Which type of cloud is associated with fair weather and has a fluffy appearance?

Cumulus clouds are indeed associated with fair weather and are characterized by their fluffy, white appearance. These clouds typically form during sunny conditions when warm air rises and cools, leading to the development of these puffy shapes. Cumulus clouds indicate a stable atmosphere and generally do not produce precipitation, making them a common sight in pleasant weather.

Stratus clouds, on the other hand, are low, gray clouds that cover the sky like a blanket and often bring overcast skies with the potential for light drizzle. Cirrus clouds are thin and wispy clouds high in the atmosphere, usually signaling a change in the weather rather than fair conditions. Nimbus clouds are associated with precipitation and stormy weather, as they are characterized by thick, dark appearances that suggest rain or storms. Thus, the distinguishing features of cumulus clouds alongside their association with fair weather set them apart from the other cloud types listed.
