Cut them out!
High Pressure
• The atmospheric pressure is
greater than its surrounding
environment.
• Happy Weather!
• Sunny Days!
H
Low Pressure
• The atmospheric pressure is
lower than its surrounding
environment.
• Lousy weather
• Rainy, cloudy, snowy
L
Cold Front
• A leading edge of a cooler
mass of air, replacing a
warmer mass of air, which lies
within a trough of low
pressure.
Looks like
Icicles hanging
Warm Front
• A leading edge of a warmer
mass of air, replacing a cooler
mass of air. Typically slower
than cold fronts.
Looks like
rising suns
Stationary Front
• A boundary between 2 different
air masses, neither of which is
strong enough to replace the
other.
Mixture of warm
and cold since
they do not replace each other.
Occluded Front
• Formed when a cold front
overtakes a warm front.
Usually forms around areas of
low atmospheric pressure.
“Suns” are now
on the same side
as the “icicles”.
Maritime Tropical Mass
• Originate over the warm waters of the
tropics and Gulf of Mexico.
• The northward movement of tropical air
masses transports warm, moist air into the
U.S., increasing the potential for
precipitation.
mT
Maritime Polar Mass
• Cool, moist, and unstable.
• The source for the air masses are the
northern Pacific and the north-western
Atlantic.
• They usually produce clouds and
precipitation as they move inland.
mP
Continental Tropical Mass
• Hot, dry air masses which originate over
northern Mexico and the southwestern
U.S.
• The leading edge of this air mass is often
called the dry line, due to the fact that they
bring in hot, dry air.
cT
Continental Polar Mass
• Cold to cool and dry, but not as cold as the
Arctic air masses, stable and usually
prevents cloud formation.
• Bring cold air during the winter and cool,
relatively clear, rather pleasant weather in
the summer.

Windy
• Wind blows because of
differences in air pressure from
one location to another.
• Wind blows from areas of high
pressure toward areas of low
pressure.

Hurricanes
1. Warm air rises, causing an area of lower
air pressure below.
2. Air from surrounding areas with higher
pressure pushes in to the low pressure
areas.
3. As the warm air continues to rise, the
surrounding air swirls in to take its place.

Rain
1. Clouds form when 2 different types of air
masses run into each other.
2. The warm air mass gets pushed up over
the cold air mass.
3. Rain occurs when the updraft dies out
and/or the drops are heavy enough to fall.
Cut them out!
Low pressure =
clouds/snow/low temps
High pressure =
sunny/clear
The low pressure will continue to
move and cause temperatures to
drop. Maybe even snow in Chicago.
Stationary front = it will
stay rainy/cloudy for a
few days
Warm front moving out =
not as warm as
yesterday/somewhat
cloudy
High pressure =
clear skies/happy
