are cumulus and cumulonimbus clouds the same?
483739
Normally, cumulus clouds produce little or no precipitation, but they can grow into the precipitation-bearing congestus or cumulonimbus clouds. ... Cumulus clouds are part of the larger category of free-convective cumuliform clouds, which include cumulonimbus clouds.

High-level clouds: The three main types of high clouds are cirrus, cirrostratus, and cirrocumulus. Cirrus clouds are wispy, feathery, and composed entirely of ice crystals. ... Unlike cirrus, cirrostratus clouds form more of a widespread, veil-like layer (similar to what stratus clouds do in low levels).

Cumuliform clouds and showery precipitation. 3413. What are characteristics of unstable air? Turbulence and good surface visibility.

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)

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.

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.

Cumulus clouds can be composed of ice crystals, water droplets, supercooled water droplets, or a mixture of them. The water droplets form when water vapor condenses on the nuclei, and they may then coalesce into larger and larger droplets.

Almost all rain is produced from low-level clouds. Stratus clouds produce steady rains, and cumulus clouds produce intense, stormy precipitation.
1071836
Cumulonimbus, from the Latin cumulus ("heap") and nimbus ("rainstorm", "storm cloud"), is a dense towering vertical cloud associated with thunderstorms and atmospheric instability, forming from water vapor carried by powerful upward air currents. ... Cumulonimbus is abbreviated Cb.
1245348
These cumulonimbus clouds (or, more commonly, rain clouds) will “stack” on top of one another, rising higher and higher, creating a tropical disturbance. ... As winds in the column start to spin faster and faster, a tropical depression, tropical storm or even a full-fledged tropical cyclone (i.e., a hurricane) can form.

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.

A cloud is made of water drops or ice crystals floating in the sky. There are many kinds of clouds.
1089145
Stratus clouds, which are the fog clouds, fall into this category. When low stratus clouds begin to deliver rain, they are called nimbostratus.
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.
859995
Cumulonimbus clouds are thunderstorm clouds that form if cumulus congestus clouds continue to grow vertically. Their dark bases may be no more than 300 m (1000 ft) above the Earth's surface. Their tops may extend upward to over 12,000 m (39,000 ft).

Howard also designated a special rainy cloud category which combined the three forms Cumulo + Cirro + Stratus. He called this cloud, 'Nimbus', the Latin word for rain. The vast majority of precipitation occurs from nimbo-form clouds and therefore these clouds have the greatest vertical height.

They form when turbulent vertical currents meet a cirrus layer, creating the puffy cumulus shape. Cirrocumulus clouds can also form through contrails, the vapour trails left by planes as they fly through a dry upper troposphere. These streaks can spread out and become cirrus, cirrostratus and cirrocumulus.
