Cumulonimbus clouds are the thunderstorm clouds par excellence. Cumulonimbus clouds can also bring dangerous winter storms (called "blizzards") which bring lightning, thunder, and torrential snow. They are the ones aircraft pilots want to steer clear of and outdoorsy people want to avoid on their favorite outings. There are three stages in the formation of cumulonimbus clouds. The lower levels of clouds mostly consist of water droplets. The name was taken from the world cumulus and nimbus. A cloud is a visible accumulation of minute droplets of wate, ice crystals, or both, suspended in the air. Small cumulus are commonly grouped with the low clouds because they do not show significant vertical extent. Cumulus clouds continue rising in shape, height, and size. Cumulonimbus clouds are the ones that produce thunder, lightning and hail, as well as very heavy bursts of rain, and so understandably many people refer to them as storm clouds. : cumulus cloud having a low base and often spread out in the shape of an anvil extending to great heights — see cloud illustration.

All Sources Fiction Arts / Culture News Business Sports Science / … Clouds are large masses of tiny water droplets (vapors) or ice crystals covered in microscopic dust particles that float in the atmosphere. Clouds form when the dewpoint temperature of water is reached in the presence of condensation nuclei in the troposphere. Well scroll down and get all the information on this cloud type, that you are looking for. A cumulonimbus cloud is one of the largest clouds formed in Earth's weather patterns. The lightning coming from the flat top is called anvil lightning. Occasionally, rising air parcels surpass the equilibrium level (due to momentum) and form an overshooting top culminating at the maximum parcel level. They have the potential to grow and form a Supercell cloud, which can be the most rigorous of thunderstorms. The cloud starts to spread out when the cooled droplets freeze and overpower the updraft. Cumulonimbus clouds span a wide range of depths, from miniature versions only about 2km deep in polar air masses over the oceans, ones that never produce lightning, to as much as 20km in the most severe thunderstorms in equatorial regions, the plains of eastern China, in Brazil and Argentina, and the plains and southeast regions of the United … By now, you may already be having a question in mind―do cumulonimbus clouds form tornadoes?

It is often accompanied by lightning, thunderstorms, and severe tornadoes. It continues to rise, gradually going above the freezing point where exist the tiny droplets and ice crystals. Furthermore, some atmospheric processes can make the clouds organize in distinct patterns such as wave clouds or actinoform clouds. The anvil or mushroom shape is caused due to the strong wind shear or warm air turbulence when the cloud reaches the troposphere. Cumulonimbus is abbreviated Cb. At this point, there can be drastic air turbulence, leading the cloud to flatten out at the top and finally manifesting as lightning, thunderstorms, and tornadoes. the "cumulonimbus cloud" family.
