Warm Up
1. Which front moves through an area faster: Cold or Warm?
2. Which property of this front explains this rate?
3. If a warm front occurs in the winter, what type of snow storm
would it likely bring?
What is the moisture content and temperature of an air mass
that formed in: (hint: wet or dry? cold or warm?)
4. Maritime Polar - mP
5. Continental Arctic - cA
Warm Up
1. Which front moves through an area faster: Cold or Warm?
Cold front because warm air is easy to push
2. Which property of this front explains this speed?
Cold is the “boss” = dense
Warm air is less dense
So the moving cold air controls what
the warm air does

Warm Up
3. If a warm front occurs in the winter, what type of snow storm
would it likely bring?
Light snow & long duration –
same effect as rain, its just a cooler temp.
Warm Up
What is the moisture content and temperature of an air mass
that formed in:
4. Maritime Polar - mP
5. Continental Arctic - cA
Warm Up
What is the moisture content and temperature of an air mass
that formed in:
4. Maritime Polar - mP
moisture = wet
temp = cold

2.5 Understand the structure of and
processes within our atmosphere.
• 2.5.1 Summarize the structure and
composition of our atmosphere.
Learning through textbook comprehension
importance of yellow atmosphere assignment
2.5.2 Explain the formation of typical air
masses and the weather systems that
result from air mass interactions.
Learning via instruction & notes
Practice through questions & exit ticket
• Explain how air masses move (pressure differentials).
• Explain how interactions of air masses form frontal
boundaries, clouds, and affect wind patterns.
2.5.3 Explain how cyclonic storms form based on
the interaction of air masses.
Write three key words from the following:
• Explain factors that affect air density and
understand their influence on winds, air
masses, fronts and storm systems.
• 􏰁Use data for explanations and provide
evidence of various air mass interactions.
• Address precautions for severe cyclonic storms
to preserve life and property.

How does the

Pressure?
Hurricanes
Tornadoes
Comparing and Contrasting Tornadoes
and Hurricanes
Hurricanes
* Form over warm water
Tornadoes
•Spinning * Form over land usually
* Greatest damage comes systems
* Greatest damage comes
from storm surges and of low
from winds
flooding
pressure
*Fujita Scale FO-F5
*Saffir Simpson Scale 1-5 •High
* Sometimes only last
* Lose speed over land speed
seconds
winds
* Predictable
* Very unpredictable and
* Big, but slow
fast
What is a Tornado?
How Do Tornadoes Form?
 Warm, humid air
collides with cold, dry
air
 The warm air rises up
through the cold air
creating an updraft
because of a LOW
PRESSURE SYSTEM
 If this updraft begins
spinning, it can turn
into a tornado
Damage Caused by Tornadoes
 Extremely high winds can tear buildings apart, slip
cars, and even suck the water out of a riverbed
 Most likely during the months
of April, May & June
Wait…how exactly does it form?

Check point #1
1. What type of pressure systems are tornadoes
associated with?
2. What causes the most damage during a tornado?
3. What is the intensity ranking for tornadoes?
Hurricane
FAST FACT
 In the Atlantic and Northeast Pacific, the term
“hurricane” is used.
 The same type of disturbance in the Northwest Pacific
is called a “typhoon”
 In the South Pacific and Indian Ocean “cyclones”
occur
Damage Caused by
Hurricanes
Most from the storm surge
and flooding!!
Most likely to occur in Late
Summer to Early Fall
FAST FACT
The word “hurricane” comes from the Taino
Native American word, Hurucane, meaning “evil
spirt of the wind.”
The first time anyone flew
into a hurricane happened
in 1943 in the middle of
WWII.
