Cirrus is a genus of atmospheric cloud generally characterized by thin, wispy strands. Stratus clouds are a genus of low-level cloud characterized by horizontal layering with a uniform base, as opposed to convective or cumuliform clouds that are formed by rising thermals, nimbus indicates a precipitating cloud. Cumulus clouds, being low-stage clouds, are generally less than 1,000 m (3,300 ft) in altitude unless they are the more vertical cumulus congestus form. Cumulus clouds may appear by themselves, in lines, or in clusters.
