 THIS
IS NOT EVERYTHING THAT CAN OR
WILL BE ON THE TEST. YOUR NOTEBOOK
IS A BETTER RESOURCE.
 BUT THIS DOESN’T HURT TO DOUBLE
CHECK.
 THIS ALSO DOESN’T MAKE ANY
CONNECTIONS FOR YOU, IT IS STRICTLY
INFORMATION
Weather fronts
Weather front
Cold
Warm
Stationary
occluded
conditions
Cold air moves in and the air mass “takes
over” the area. Warm air rises above the cool
air (because its less dense). Cold front move
more quickly than warm front and brings
rainy and stormy weather.
Moves slower, brings long periods of
light/medium rain
A cold front and a warm front meet but do
not have enough energy to collide. They are
“stuck” in their place.
When a cold front catches up to a warm front
and forces the air upward so two cold fronts
are next to each other

Weather forecasting
-Using fronts, pressure systems and air masses to predict what
weather will be like for certain areas based on these factors.
-We practiced this in class on “The WeatherCycler”
Can you name where the High
pressure areas are? Low pressure?
Can you say where the fronts are
AND what types?
If you can can you PREDICT
where the wind will come from in
cities around the pressure systems?
Can you Predict what the
temperature will be like in certain
area after some time has passed?
(JUST ideas- not everything)
Severe Weather
Types
Tornado
-come from thunderstorms
-Fujita scale
-Oklahoma is the “Tornado Capital”
Hurricane
-winds over 75 mph
-warm tropical water
-center is called the “eye”
-in Asia they are called typhoons
Thunderstorm
-3 stages: cumulus, mature, dissipation
-features: heavy rain, high winds, lightning, and hail
-average time: 10-12 minutes
