      From the BBC’s Weather Watchers website come three nice photo of Shelf Clouds.

      I think, and I stand to be corrected on this, the name Shelf Cloud is another term for Roll Cloud.

      Whatever, just enjoy.

      Yep, enjoyable, Laurence, thanks.

      But the CAS gospel (Handbook) gives arcus (p53) as the pertinent supplementary feature; arcus protuding forward becomes shelf; more rarely arcus separating becomes roll (p53) – most roll clouds are types of arcus (p67).
