WEATHER PATTERNS
Clouds 6.1
CONDENSATION
When molecules of water
vapor in the air become
liquid water.
Condensation is what leads
to cloud formation.
What else do you need to
form a cloud?
Particles – dust, salt, pollen,
etc.
DEW POINT
Frost on leaf
The temperature at
which condensation
begins.
Liquid water that
condenses from air onto
a cooler surface is
called dew.
Ice deposited on a
surface below freezing
is called frost.
CLOUDS FORM WHEN
WARM, MOIST AIR RISES
AND COOLS.
particles
condensation
cools
CIRRUS
Wispy, feathery
clouds.
Cirrus = “a curl”
Usually indicates fair weather.
CUMULUS
Fluffy, white
clouds, usually
with flat bottoms.
Cumulus = “heap”
The next 2 slides have examples of
neat cloud shapes. What do you
see?
STRATUS
Clouds that form in
flat layers and
often cover much
of the sky.
Stratus = “spread out”
