Cumulonimbus (from Latin cumulus 'swell' and nimbus 'cloud') is a dense, towering, vertical cloud, [1] typically forming from water vapor condensing in the lower troposphere that builds upward carried by powerful buoyant air currents.

2024年6月2日 · Cumulonimbus clouds are the most iconic, beloved and feared clouds on our planet. They are certainly the most impressive, rolling out from over the horizon like a vengeful wave of anger and retribution.

What are cumulonimbus clouds? Cumulonimbus clouds are menacing looking multi-level clouds, extending high into the sky in towers or plumes. More commonly known as thunderclouds,...

The cumulonimbus cloud, or thunderstorm, is a convective cloud or cloud system that produces rainfall and lightning. It often produces large hail, severe wind gusts, tornadoes, and heavy rainfall. Many regions of the earth depend almost totally upon cumulonimbus clouds for rainfall.

2024年5月21日 · A cumulonimbus cloud is one of the largest clouds formed in Earth's weather patterns. The tall, column-like appearance, often with a flat top, can indicate severe lightning, heavy rain and high winds.

Towering cumulonimbus clouds rise thousands of metres, producing violent thunderstorms and releasing latent heat in the surrounding air. As a result, the upper tropospheric warm belt migrates northwestward from the ocean to the land.

2024年12月20日 · Cumulonimbus clouds are towering clouds associated with thunderstorms and atmospheric instability. Cumulonimbus clouds form through a process of intense vertical development, reaching high altitudes in the atmosphere.

Learn about cumulonimbus clouds, including cloud description and facts, images, how to best identify them, and their species, varieties, and features.

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. Fueled by vigorous convective updrafts (sometimes in excess 50 knots), the tops of cumulonimbus clouds can easily reach 39,000 feet (12,000 meters) or higher.
