Cloud Showcase: Cumulus humilis


Cumulus humilis above Upper Newport Bay Nature Preserve in Newport Beach, CA

Cumulus is Latin for heap and humilis means low or shallow, which is just what you see here.     Cumulus humilis clouds are usually between 2,000-3,000 ft. altitude and are frequently seen over land.  When enough moisture and convective current is present, then can build into Cumulus mediocris or occasionally into a Cumulas congestus.   The humilis variety is somewhat short and wide, do not cause precipitation and are a sign of fair weather.
