Cumulonimbus ( Cb ) is a type of cloud that is tall, dense, and involved in thunderstorms and other intense weather. It is a result of atmospheric instability. These clouds can form alone, in clust...

These clouds are named because they are puffy ("cumulo") and because they often are dark clouds which cause rainstorms ("nimbus"). Cumulonimbus clouds are different because they cannot be classified as low, middle or high altitude clouds.

Cumulonimbus clouds (Cb) are much larger and more vertically developed than fair weather cumulus. They can exist as individual towers or form a line of towers called a squall line.

Cumulonimbus clouds belong to the Clouds with Vertical Growth group. They are generally known as thunderstorm clouds. A cumulonimbus cloud can grow up to 10km high. At this height, high winds will flatten the top of the cloud out into an anvil-like shape.

line. They create lightning throught the heart of the cloud. Cumulonimbus clouds form from cumulus cloud ... Cumulonimbus clouds usually form from cumulus clouds at a much lower height, thus making them, like cumulus clouds, grow vertically instead of horizontally, thus giving the cumulonimbus its mushroom shape.

Cumulonimbus cloud, characterized by strong vertical development in the form of mountains or huge towers topped at least partially by a smooth, flat, often fibrous anvil. Also known colloquially as a "thunderhead." The flat, spreading top of a Cb (cumulonimbus) is often shaped like an anvil and therefore named anvil.

The cloud that forms is called cumulonimbus. It resembles cumulus but towers much higher, with a base at 1,000-5,000 ft (300-1,500 m). Rain starts to fall. Inside this very violent cloud, air rises rapidly in the convection cells and sinks between them.

Cumulonimbus clouds are much larger and more vertically developed than cumulus clouds which form in a more stable atmosphere. They can exist as individual towers or form a line of towers called a squall line often present at cold fronts.
