- Cloud types, Cb: line of Cumulonimbus clouds
- W923306S
- Cloud types, Cb: this wall and line of Cumulonimbus clouds has a base near the horizon along a wind shift line, with a large, fibrous anvil above with hints of an outer ghost anvil. The bank of Cumulus across the view is moving away from the storm along an outflow boundary. The storm seems to have no new development, but this is not true; it is hidden from view on the other side of the line.
