- Description of a Cumulonimbus cloud type. Cloud types, Cb: bright cloud towers comprise the base of a Cumulonimbus cloud. Above them, a very high anvil spreads out like a gray pancake. The extreme wide view brings these together in one scene, but the anvil's horizontal extent is obvious from its dull, shaded appearance.
