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...

Clouds form when the dewpoint of water is reached in the presence of condensation nuclei in the troposphere. Atmosphere is a dynamic system, and the local conditions of turbulence, uplift and other pa...

Cumulonimbus clouds form in unstable, moist atmospheres and are common in spring and summer. They often occur in the advance of a cold front. In summer they can form over mountains due to orographic lifting in combination with solar heating.

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 hig...

1) The clouds must be driven or "pushed" by the wind: Cumulonimbus clouds form when prevailing winds push smaller fragments of clouds (called cumulus clouds) to a place where these clouds mix together. (See below)

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.

How Do Clouds Form?; A complete description follows this diagram: ... This is how cumulus congestus and cumulonimbus clouds form. If air parcels only rise a short distance over a large geographical area after reaching dewpoint, layer clouds (such as stratus) will form.
