Predict the Weather by learning Cloud Types
High Clouds
Cirrus Clouds appear about 24-36 hrs before a
change in the weather
More Cirrus Clouds
Middle Clouds
Altocumulus clouds are about the size of your thumb when held at arms length.
Middle Clouds
Altostratus are a thinner form of
stratus clouds found higher in the atmosphere
Low Clouds
Nimbostratus are rain-bearing clouds that cover the sky in one
large layer.
Low Clouds
Cumulus clouds are puffy, and form individually, or as one large thunderstorm.
Clouds that grow…
Cumulonimbus clouds are thunderstorm
clouds!
Another growing cloud…
This cumulonimbus was photographed from an

A Severe Storm Cloud Mammatus clouds are
often seen before a tornado or funnel cloud appears
Severe Storm Cloud A Wall Cloud signals an approaching front
How Do Clouds Form?1. Warm, humid air near the
ground is heated.
2. The Warm Air rises.
3. The air cools as it rises.
4. The temp. of the air reaches the dewpoint temp.
5. The water changes from a gas to liquid water.
DEWPOINT!!!Dewpoint temperature
always has to be the same or less than the air temperature.
What do we see when the air temp and dewpoint are the same at ground level?
