Chapter 24 Weather
Standards
5a. Students know how differential heating of Earth results in circulation
patterns in the atmosphere and oceans that globally distribute heat.
6a. Students know weather and climate involve the transfer of energy into and
out of the atmosphere

Air Masses
• AIR MASS= large body of air throughout which
temp. and moisture are similar
• 4 types:
Continental
Maritime
Tropical
Polar
Fronts
• FRONTS= the boundary of an air mass when 2
air masses of different temps/moisture collide
• COLD FRONT= when a cold air mass overtakes
a warm air mass. If the warm air is moist,
clouds will form and thunderstorms will result.
• WARM FRONT= when a cold air mass leaves, a
warm front moves in. Results in precipitation
over a large area.
• OCCLUDED FRONT=fast moving cold air mass
lifts warm air off the ground
Severe Weather
Tornadoes
• Rotating column
of air with high
winds
• Forms when a
thunderstorm
meets high
altitude
horizontal winds
Thunderstorms
• Rain, thunder,
lightning, strong
winds
• Lightning=cloud
s discharging
electricity.
Noise is
Thunder.
Hurricanes
• Develop over
warm oceans
• Most dangerous
part of hurricane
is STORM SURGE;
rising sea level
and large waves

pressure
