1.High clouds (40,000 to 20,000 above from the surface of
ground) mainly they are cirrus clouds (Ci)
2.Middle clouds (20,000 to 7000) they are alto clouds (At)
3.Low clouds (lower then 7000 ) mainly they are stratus
clouds (St)
4.Vertically extended clouds they are cumulus clouds (Cu)
Names for Clouds
The names for clouds are combination of prefix and suffix
stratus/strato = flat layer and smooth
• Cumulus/cumulo = heaped up or fluffy
• Cirrus/ cirro = high up or feathers like
• Alto = medium level
• Nimbus/Nimbo = rain bearing clouds
High clouds (Cirrus)

• High clouds are of three types


1. Cirrus clouds
2. Cirrocumulus clouds
3. Cirrostratus clouds
Cirrus clouds

The higher
altitudes detached
clouds having
silky appearance

They are
composed of tiny
crystal therefore
they do not cause
rainfall
often called
Mare’s tail
Cirrocumulules

and spread in the
sky like milky thin
sheet .

These are
transparent clouds
and create halo
Middle clouds Alto (At)

•Middle clouds are of two types


1. Altocumulus clouds
2. Altostratus clouds
Altocumulus clouds

characterized by
white wavey layer or
globular forms
these clouds form a
fairly regularly
patterns of line
these clouds are
often called as sheep
clouds they normally
indicate fine weather
Altostratus clouds

They are thin sheet of


gray blue clouds having

then nimbous clouds but
darker then cirrus
when they become thick
sheet sun or moon
become faintly visible
behind them
Low clouds mainly stratus clouds
( st )
• Low clouds are of three types
1.stratus clouds
2. stratocumulus clouds
3. nimbostratus clouds

dense low
lying dark gray
colour clouds

ground surface
.

Bring dull
Stratocumulus
clouds

These are light


gray colour
clouds .

composed of
globular masses
arranged in line ,
waves or group .

low clouds of dark


colour , very close to
the ground surface.
They create
darkness because
sunlight is obscured
due to high
thickness , increase
humidity in
atmosphere, known
as rain clouds .
Vertically extended clouds (nimbus)
