What type of cloud is typically associated with precipitation?

Nimbostratus clouds are thick, dark clouds that cover the sky and are typically associated with continuous, steady precipitation. These clouds form in stable atmospheric conditions and extend over large areas, often resulting in the consistent rain or snow that is characteristic of these types of clouds. The very structure of nimbostratus clouds, which contains ample moisture and covers the sky uniformly, leads to prolonged precipitation events that can last for several hours or even days.

Cumulus clouds, while often seen during fair weather, are generally not associated with significant precipitation; they may occasionally produce light rain or showers. Cirrus clouds are high altitude, thin clouds that do not produce precipitation at the surface. Stratus clouds can bring light rain or drizzle but are not typically known for the heavier, continuous precipitation associated with nimbostratus clouds.
