Cumulonimbus Clouds reaching high into the atmosphere
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.
Cumulonimbus (Cb) A principal cloud type (cloud genus) of vertical development. Exceptionally dense and vertically developed clouds, occurring either as isolated clouds or as a line or wall of clouds with separated upper portions.

Cumulonimbus - A dense and vertically developed cloud that produces thunderstorms. The cloud can bring heavy showers, hail, lightning, high winds and sometimes tornadoes.
Cumulonimbus clouds showing strong updrafts.
These clouds can have strong upcurrents, rise far above their bases and can form at many heights.

Cumulonimbus
sometimes called thundercloud. The largest single cloud in the sky and can have a base of 2000 feet and tops of 40000 feet in temperate latitudes and even larger in the tropics.
Cumulus ...
CUMULONIMBUS - A cumulus cloud that has precipitation associated with it. The term CUMULO is Latin derived meaning "heaped up" and NIMBUS is Greek derived word for "rain". Cumulonimbus clouds can occur at any altitude and often vertically developed.
Cb - Cumulonimbus cloud
Ceiling - The height of the lowest layer of broken or overcast clouds.
Ceilometer - A device used to evaluate the height of clouds or the vertical visibility into a surface-based obscuration.
Pyrocumulus clouds: Cumulus cloud forms formed by fire, usually large wildfires. Similarly, pyrocumulonimbus, cumulonimbus clouds formed by fire.

capillatus"See cumulonimbus capillatus, cloud classification.
capped column"A form of ice crystal consisting of a hexagonal column with plate crystals or stellar crystals at its ends and sometimes at intermediate positions.
Congestus (or Cumulus congestus)A large cumulus cloud with great vertical development, usually with a cauliflower-like appearance, but lacking the characteristic anvil shaped top of a Cb (Cumulonimbus cloud).
In the mid-latitudes, cloud bases are usually found between 20,000 to 30,000 feet, and it is the highest cloud that forms in the sky, except for the tops, or anvils, of cumulonimbus, which occasionally build to excessive heights.
ThunderstormA local storm produced by a cumulonimbus cloud and accompanied by lightning and thunder.Tidal CycleThe periodic changes in the intensity of tides caused primarily by the varying relations between the earth, moon, and sun.
AnvilThe flat, spreading top of a cumulonimbus cloud, often shaped like an anvil. Thunderstorm anvils may spread hundreds of miles downwind from the thunderstorm itself, and sometimes may spread upwind.
Thus, a cumulonimbus cloud is said to have a "glaciated" upper portion.GlacierIn hydrologic terms, bodies of land ice that consist of recrystallized snow accumulated on the surface of the ground, and that move slowly downslope.
The most common source of lightning is the electric charge separated in ordinary thunderstorm clouds (cumulonimbus). Well over half of all lightning discharges occur within the thunderstorm cloud and are called intracloud discharges.
The stones fall from cumulonimbus clouds.hailstonesTransparent or partially opaque particles of ice that range in size from that of a pea to that of golf balls.

cumulonimbus (thunderhead) forms by vertical growth (upward convection) of cumulus cloud

In the 'Low' cloud classification come: Stratus (St); Stratocumulus (Sc); Cumulus (Cu) and Cumulonimbus (Cb).
ANVIL The upper portion of a cumulonimbus cloud that becomes flat and spread-out, sometimes for hundreds of miles downstream from the parent cloud. It may look smooth or fibrous, but in shape, it resembles a blacksmith's anvil.
Tornado: Extension of the base of a Cumulonimbus cloud, in the form of funnel, which, circulating fast, goes down to the surface of the Earth, where it produces as strong whirlwind capable of causing great destruction.
Eyewall / Wall Cloud: An organized band or ring of cumulonimbus clouds that surround the eye, or light-wind center of a tropical cyclone. Eyewall and wall cloud are used synonymously.
Showery precipitation in the form of irregular pellets or balls of ice more than 5 mm in diameter, falling from a cumulonimbus cloud.

The tornado usually appears from a bulge in the base of a cumulonimbus cloud. It has a typical width of tens to hundreds of meters and a lifespan of minutes to hours.
A strong downdraft current of air from a cumulonimbus cloud, often associated with intense thunderstorms. Downdrafts may produce damaging winds at the surface.

Waterspout - A rapidly rotating column of air extending from a cumulonimbus cloud with a circulation that reaches the surface of the water, (i.e. a tornado over water).

Funnel Cloud- a funnel shaped cloud that extends from a cumulus or cumulonimbus cloud; this cloud is related to a rotating column of air that is not in contact with the ground.

Hail is produced when large frozen raindrops, or almost any particles, in cumulonimbus clouds act as embryos that grow by accumulating supercooled liquid droplets.
hail: precipitation composed of chunks of ice that form atop cumulonimbus clouds and fall as soon as they become too heavy for the cloud updrafts to hold.
Anvil Cloud
A Cirriform cloud, with an anvil shape, which forms the upper part of a well-developed Cumulonimbus. Its glaciated top spreads out horizontally upon reaching the tropopause or by the action of the winds aloft.
A local storm, usually produced by a cumulonimbus cloud (thunderhead), and accompanied by thunder and lightning.
Tidal bore ...
Eye Wall - The doughnut-shaped area ofintensive cumulonimbus development and very strong winds that surrounds the eye of a hurricane.
This plays a role in the complex phenomena of the cumulonimbus. Electrical charge is separated when water droplets are formed, and this causes lightning and a thunderclap.
Solid precipitation in the form of chunks or balls of ice with diameters greater than 5 mm. The stones fall from cumulonimbus clouds.
