3. How clouds form
Small drops of water turn into a gas called water
vapor
Once the vapor reaches a certain altitude the
cold air causes the water droplets to start to
stick together.
4. How Clouds Are Named
The height at which the cloud is located contributes
to the naming.
A clouds shape helps decide between the types of
clouds.
5. Types of clouds
Type 1: High Clouds
Type 2: Mid Clouds
Type 3: Low Clouds
Type 4: Vertically Developed Clouds
7. Cirrus
Look like feathers.
First to appear when the skies are clear.
Shape and movement of the cloud indicates the strength and
speed of the high altitude winds.
Don’t produce rain or snow at the Earth’s surface.
8. Cirrocumulus
Look like cotton balls unrolled
Can appear in rows or
Individually
Their rippling appearance helps with their identification.
9. Cirrostratus
Thin blanket of clouds that covers the sky.
The clouds are so thin that the moon and sun shine through.
Form at about 4 miles above the ground
Signals rain
12. Altostratus
Consists of both water droplets and ice crystals
Cover large amounts of the sky
“frost” the sky.
Small amounts of precipitation
Rain is possible
13. Altocumulus
Can be white, grey or both.
Looks like bubble (foam) in a hot tub
Easy to mix up with high clouds because sometimes the
shading is not visible.
21. Cumulus
Looks similar to cotton wool
Have shapes sometimes
Clumps of clouds are spaced out allowing the pretty blue sky
to shine through.
Looks like a rooster.
22. Cumulonimbus
Tall
Can move into the stratosphere
Contains both water droplets and ice crystals
Produce different weather conditions
Vertical wind can reach high speeds
