Stratocumulus Congestus

Stratocumulus Congestus

A peculiar mound of dense convection welled up in seemingly boiling fashion, leading to a doming effect in an otherwise benign field of stratocumulus. The upward motion in this dome was strong enough that a moat of subsidence (and resultant clearing) partially encircled it, showing up best on the left and upper sides. Although I don't know of any such "official" nomenclatural combination yet, the densely packed, relatively deep feature has all the characteristics of congestus, but in a field of stratocumuli--hence the name stratocumulus congestus that I have given to it.
