Nimbus (weather phenomenon)

Nimbus is a term used to describe a type of cloud associated with precipitation, indicating that rain, snow, or other forms of moisture are falling from the sky. The word "nimbus" is derived from Latin, meaning "rainstorm" or "cloud." In weather observation, clouds classified as nimbus types—such as cumulonimbus or stratus nimbus—are typically heavy, thick, and capable of producing significant weather events like thunderstorms, heavy rain, or snow. These clouds play a key role in the Earth's water cycle by facilitating the transfer of moisture from the atmosphere to the surface.
