A nimbus cloud is a cloud that produces precipitation. Usually the precipitation reaches the ground as rain, hail, snow, or sleet. Falling precipitation may evaporate as virga.
Since nimbus clouds are dense with water, they appear darker than other clouds. Additionally, nimbus clouds can be characterized by their great height. Nimbus clouds are formed at low altitudes and are typically spread uniformly across the sky.

Famous quotes containing the word cloud:
“The cloud was so dark that it needed all the bright lights that could be turned upon it. But for four years there was a contagion of nobility in the land, and the best blood North and South poured itself out a libation to propitiate the deities of Truth and Justice. The great sin of slavery was washed out, but at what a cost!”
—M. E. W. Sherwood (1826–1903)
