Which type of cloud is associated with precipitation?

Nimbostratus clouds are known for their association with continuous precipitation. These clouds typically appear as thick, dark layers that cover the sky and can produce steady rain or snow over extended periods. Their uniform appearance and consistent precipitation make them distinct from other types of clouds, which might not always lead to rainfall.

Cumulus clouds, while they can develop into larger storm systems, generally indicate fair weather and are not primarily associated with precipitation. Stratus clouds can produce light precipitation, such as drizzle, but the intensity and duration are not comparable to that of nimbostratus clouds. Cirrus clouds, high in the atmosphere, are typically thin and wispy and do not produce precipitation directly at the surface. They may indicate changing weather patterns, but they are not a source of significant precipitation.

Overall, the defining characteristic of nimbostratus clouds is their ability to deliver persistent, widespread rainfall, which clearly distinguishes them in this context.
