Do You Know these Facts About Clouds ?
Clouds are a complex product of our atmosphere
Clouds form when humid air cools enough for water vapor to condense
into droplets or ice crystals. The altitude at which this happens
depends on the humidity and the rate at which temperature drops with
elevation.Do You Know these Facts About Clouds ?
Normally, water vapor can only condense onto condensation nuclei—tiny
particles that serve as kernels around which drops can form.
Cloud Types
Clouds are classified into four basic categories, depending largely on the height of their bases above the ground.
High-level clouds, called cirrus clouds, can reach heights of 20,000
feet (6,000 meters) and are typically thin. They do not produce rain and
often indicate fair weather. They are usually made up of ice.
Do You Know these Facts About Clouds ?
Midlevel clouds form between 6,500 feet (2,000 meters) and cirrus
level. They are referred to as "alto-" clouds and bear such names as
altostratus or altocumulus, depending on their shape. (Altostratus
clouds are flat; altocumulus clouds are puffy.) They frequently indicate
an approaching storm.
They themselves sometimes produce virga, which is
rain or snow that does not reach the ground.
Low-level clouds lie below 6,500 feet (2,000 meters). Meteorologists
refer to them as stratus clouds. They're often dense, dark, and rainy
(or snowy) though they can also be cottony white clumps interspersed
with blue sky.

Storm Clouds
The most dramatic types of clouds are cumulus and cumulonimbus, or
thunderheads. Rather than spreading out in bands at a fairly narrow
range of elevations, like other clouds, they rise to dramatic heights,
sometimes well above the level of transcontinental jetliner flights.
Cumulus clouds are fair-weather clouds. When they get big enough to
produce thunderstorms, they are called cumulonimbus.
Do You Know these Facts About Clouds ?
These clouds are
formed by upwelling plumes of hot air, which produce visible turbulence
on their upper surfaces, making them look as though they are boiling.
Just as it takes heat to evaporate water from the surface of the Earth,
heat is released when water condenses to form clouds. In thunderheads,
this energy can produce hail, damaging winds, lightning, torrential
rain, and sometimes tornadoes.
Do You Know these Facts About Clouds ?
As thunderheads reach high elevations, their tops encounter high
winds that cause them to spread out sideways, earning them the nickname
"anvil tops." They can reach elevations of 50,000 feet (15,000 meters).
