Clouds are divided into two general categories: layered and convective. These are named stratus clouds (or stratiform, the Latin stratus means "layer") and cumulus clouds (or cumuliform; cumulus means "piled up"). These two cloud types are divided into four more groups that distinguish the cloud's altitude. Clouds are classified by the cloud base height, not the cloud top. This system was proposed by Luke Howard in 1802 in a presentation to the Askesian Society.


High clouds (Family A)
These generally form above 16,500 feet (5,000 m), in the cold region of the troposphere. However, in Polar regions, they may form as low as 10,000 ft (3,048 m). They are denoted by the prefix cirro- or cirrus. At this altitude, water frequently freezes so clouds are composed of ice crystals. The clouds tend to be wispy, and are often transparent.

Clouds in Family A include:

Cirrus (CI)
Cirrus uncinus
Cirrus Kelvin-Helmholtz Colombia
Cirrostratus (Cs)
Cirrocumulus (Cc)
Pileus
Contrail, a long thin cloud which develops as the result of the passage of an aircraft at high altitudes.

Middle clouds (Family B)

Altocumulus mackerel skyThese develop between 6,500 and 16,500 feet (between 2,000 and 5,000 m) and are denoted by the prefix alto-. They are made of water droplets and are frequently supercooled.

Clouds in Family B include:

Altostratus (As)
Altostratus undulatus
Altocumulus (Ac)
Altocumulus undulatus
Altocumulus mackerel sky
Altocumulus castellanus
Altocumulus lenticularis

Low clouds (Family C)

Low cloudsThese are found up to 6,500 feet (2,000 m) and include the stratus (dense and grey). When stratus clouds contact the ground, they are called fog.

Clouds in Family C include:

Stratus (St)
Nimbostratus (Ns)
Cumulus humilis (Cu)
Cumulus mediocris (Cu)
Stratocumulus (Sc)

Vertical clouds (Family D)

Cumulonimbus clouds showing strong updraftsThese clouds can have strong up-currents, rise far above their bases and form at many heights.

Clouds in Family D include:

Cumulonimbus (associated with heavy precipitation and thunderstorms) (Cb)
Cumulonimbus incus
Cumulonimbus calvus
Cumulonimbus with mammatus
Cumulus congestus
Pyrocumulus

Mammatus cloud formations

Other clouds
A few clouds can be found above the troposphere; these include noctilucent and polar stratospheric clouds (or nacreous clouds), which occur in the mesosphere and stratosphere respectively.


Cloud fields
A cloud field is simply a group of clouds, but sometimes cloud fields can take on certain shapes that have their own characteristics and are specially classified. For example, stratocumulus clouds can often be found in the following forms:

Open cell, which resembles a honeycomb, with clouds around the edges and clear, open space in the middle.
Closed cell, which is cloudy in the center and clear on the edges, similar to a filled honeycomb.
Actinoform, which resembles a leaf or a spoked wheel

There are ten major cloud types
Low Level cloud:
Stratus (St)
Stratocumulus(Sc)
Cumulus (Cu)
Cumulonimbus(Cb)

Middle Level cloud:
Altocumulus (Ac)
Altostratus (As)
Nimbostratus (Ns)

High Level cloud:
Cirrus (Ci)
Cirrostratus (Cs)
Cirrocumulus(Cc)

The World Meteorological Organisation recognises 27 types of cloud that are coded in weather reports, 9 low, 9 middle and 9 high level clouds. For example, the low level clouds are:
1 Cumulus of small vertical extent
2 Cumulus of great vertical extent
3 Cumulonimbus without an anvil
4 Stratocumulus formed from the spreading out of cumulus
5 Stratocumulus
6 Stratus of fair weather
7 Stratus of bad weather
8 Cumulus and stratocumulus with bases at different levels
9 Cumulonimbus with an anvil

There are many variations of clouds which can be remarked upon such as mammatus and pileus caps.

When you first said Cloud, I immediately thought of the Final Fantasy character Cloud Strife. He could be in for some teasing at school. If you seriously consider naming him Cloud, my advice would be to make it a middle name not a first. Otherwise, you could just reconsider your choices. How about Claude as an alternative? Claude McCoy If you fancy Cl- names, there's Claiborne, Cleon, Clive. Other names that go well with McCoy are: Breckin Camden Cillian (pronounced KILL ian) Leander Lucius Logan Maverick Robert

There are 10 types of clouds. Five of them are low altitude clouds. They are called stratus, cumolonimbus, cumulus, nimbostratus and stratocumulus. Altrocumulus and Altostratus are middle altitude clouds. The last three are high altitude clouds which usually have ice in them since they are so cold. They are cirrocumulus, cirrostratus and cirrus clouds.

Stratiform, cumuliform and cirriform

layered, heaped and wispy ice clouds in that order.

the heaped clouds are formed by convection (rising warm air)

The wispy ice clouds are formed at very high levels and are often the first signs of an approaching front

When i studied meteorology there were 99 types and I'm not listing all of those!
