where are cumulonimbus clouds in the sky?
439671
Appearance. Towering cumulonimbus clouds are typically accompanied by smaller cumulus clouds. The cumulonimbus base may extend several miles across and occupy low to middle altitudes - formed at altitude from approximately 200 to 4,000 m (700 to 10,000 ft).

A cloud is made of water drops or ice crystals floating in the sky. There are many kinds of clouds.

['Stratus/strato = flat/layered and smooth.', 'Cumulus/cumulo = heaped up/puffy, like cauliflower.', 'Cirrus/cirro = high up/wispy.', 'Alto = medium level.', 'Nimbus/Nimbo = rain-bearing cloud.']

Clouds that produce rain and snow fall into this category. ("Nimbus" comes from the Latin word for "rain.") Two examples are the nimbostratus or cumulonimbus clouds. Nimbostratus clouds bring continuous precipitation that can last for many hours.

Cumulonimbus clouds are born through convection, often growing from small cumulus clouds over a hot surface. ... They can also form along cold fronts as a result of forced convection, where milder air is forced to rise over the incoming cold air.

The different types of clouds are cumulus, cirrus, stratus and nimbus.

Fair weather cumulus have the appearance of floating cotton and have a lifetime of 5-40 minutes. Known for their flat bases and distinct outlines, fair weather cumulus exhibit only slight vertical growth, with the cloud tops designating the limit of the rising air.

A typical cumulus cloud is about a cubic kilometer in volume, and has about 500 tons of water. Larger clouds can be much, much heavier. A big stormcloud could have over a million tons of water.
1283963
Low level clouds. Clouds with a base below 6,500 ft including cumulus, cumulonimbus, stratocumulus and stratus.
1190363
High-level clouds (5-13 km): cirrocumulus, cirrus, and cirrostratus. Mid-level clouds (2-7 km): altocumulus, altostratus, and nimbostratus. Low-level clouds (0-2 km): stratus, cumulus, cumulonimbus, and stratocumulus.

The types of clouds can be divided into three levels, each in turn with its own main groups of clouds. All in all, there are ten fundamental types of clouds. Often, you'll some places simply class clouds as cirrus, stratus, and cumulus because these clouds are the most common and representative for each altitude class.
117053
Thus, the 10 types are: Low-level clouds (cumulus, stratus, stratocumulus) that lie below 6,500 feet (1,981 m) Middle clouds (altocumulus, nimbostratus, altostratus) that form between 6,500 and 20,000 feet (1981–6,096 m) High-level clouds (cirrus, cirrocumulus, cirrostratus) that form above 20,000 feet (6,096 m)

There are many different types of clouds in the sky, but did you know that some of them are man-made? ... That little cloud is formed by the water vapor in your breath, which is normally invisible. In cold weather, however, the vapor condenses into a visible cloud. Contrails are formed in much the same way.

Cumulus clouds result from air rising due to positive buoyancy (i.e. metaphor: bubbles rising in a pot of water). Stratus clouds results from a forced lifting of air (low level convergence, upper level divergence). Cumulus clouds are associated with convection.

Cirrocumulus clouds are usually seen in the winter and indicate fair, but cold weather. In tropical regions, they may indicate an approaching hurricane. Altostratus clouds are gray or blue-gray mid level clouds composed of ice crystals and water droplets. The clouds usually cover the entire sky.
1042066
The list of cloud types groups the main genera as high (cirrus, cirro-), middle (alto-), multi-level (nimbostratus, cumulus, cumulonimbus), and low (stratus, strato-) according to the altitude level or levels at which each cloud is normally found.
1325597
Cirrocumulus clouds are made up of lots of small white clouds called cloudlets, which are usually grouped together at high levels. Composed almost entirely from ice crystals, the little cloudlets are regularly spaced, often arranged as ripples in the sky.
