- Cloud types, Cb: a small Cumulonimbus cloud rises
- W020326Z
- Cloud types, Cb: a small Cumulonimbus cloud pokes above a group of lower Towering Cumulus. The anvil has just formed and a new updraft spurts through it briefly to form an overshoot. Such a pulse-type storm is a single event which will collapse under its own downdraft from lack of winds aloft to ventilate anvil material away from the updraft.
