evaporation.

Weather Changes As Air Masses
Move
Air Masses Are Bodies of Air That Move
Through The Atmosphere
• Air Mass – A large volume of air in which
temperature and humidity are nearly the
same in different locations at the same
altitude.
• An air mass forms when the air over a large
region of Earth sits in one place for many
days. The air gradually takes on the
characteristics of the land or water below it.
• Earths surface can affect the air on Earth.
The Four Types of Air Masses
• Continental air masses form over land. Air
becomes dry as it looses moisture.
• Maritime air masses form over water. Air
becomes moist as it gains water vapor.
• Tropical air masses form near the equator.
Air becomes warm as it gains energy from
the warm land or water below.
• Polar air masses form far from the
equator. Air becomes cool as it loses
energy from the cold land or water below.
How Air Masses Move
• Air masses can travel away from the
regions where they form. They move with
the global pattern of winds.
• When an air mass moves to a new region,
it carries along its characteristic moisture
and temperature.
Cold Front
• Front – A boundary
between air masses.
• Cold fronts can move
into regions quickly. A
front is steeper then
any other fronts. Cold
fronts often produce
cumulonimbus
clouds, which can
cause heavy storms.
Cold Front
Warm Front
• Warm fronts move more
slowly than cold fronts.
Warm air moves up and
over a mass of denser
and colder air. As a warm
front approaches, you
may first see high cirrus
clouds, then stratus
clouds, then lower stratus
clouds. Often a warm front
brings many hours of
steady rain or snow.
Warm Front
Stationary Front
• Stationary fronts
occur when air
masses first meet or
when a cold or warm
front stops moving.
For a while the air
masses stay in the
same location. If the
air pushes up it may
produce clouds that
cover the sky.
Stationary Front
Pressure Systems
• High-pressure system is formed when air
moves all the way around a high-pressure
center. Generally brings clear skies and
calm air or gentle breezes.
• Low-pressure system is a large weather
system that surrounds a center of low
pressure. Usually develops between a
warm air mass and a cold air mass.
