• The Clouds

2
Clouds form when the air temperature cools and
causes water vapor in the air to condense into
tiny drops of water.
3
As you can see there are many different types of
clouds. They form as high as 40,000 feet and as
low as 1 foot.
4
There are three basic types of clouds, Cirrus,
Stratus, and Cumulous.
5
CIRRUS CLOUDS - These high altitude clouds are
made up of tiny ice crystals. These are wispy
clouds.
6
Cirrus generally occur in fair weather and point
in the direction of air movement at their
elevation.
7
These clouds are called Stratus clouds. These are
the gray clouds you see on rainy days.
8
STRATUS CLOUDS form a low layer of dark gray
clouds, they form along warm fronts and can bring
light rain or snow showers.
9
CUMULUS CLOUDS These puffy cotton-ball clouds
begin to form when water droplets condense at
middle altitudes.
10
Cumulus clouds signify a change in the weather.
11
These clouds can become Cumulonimbus clouds.
These occur when a cold front moves through.
12
CUMULONIMBUS are the towering clouds you see
just before it rains. These are where the
thunder storms form.
