Transcript HuRrIcAnEs vs. ToRnAdOeS!

Objective: Describe and analyze the formation of
severe weather.
Do Now!
1. What would you do if you were told that
there was a chance that the place where you
live would be destroyed by a large storm (but
you’ve been told this before)? Would you
evacuate and leave your life behind you, or
take the risk and stay.
EXPLAIN in at least 3-4 sentences
Math EOC Review
 Problem:
 How can we make these reviews more helpful?

Hurricane and Tornado Search
 Textbook page. 573-577
 Quietly in your seat, take 15 minutes to complete your
graphic organizer
 As you go, consider similarities and differences
between the 2 storms
CYCLON What is it?
IC
SYSTEM
Tornad

Hurrica
nes
How does the
storm develop?
How often does
this storm
occur?
What is the
intensity
ranking?
Associated
with High
or Low
Pressure?
What is a Tornado?
How Do Tornadoes Develop?
 Warm, humid air
collides with cold, dry
air
 The warm air rises up
through the cold air
creating an updraft
 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
Tornado in Joplin, Missouri
May
2011
STORM CHASERS VIDEO
 http://www.youtube.com/watch?v=65Su8wpmFu8
Why was this tornado in Joplin so destructive?
What damage resulted from this cyclonic storm?
What intensity rating did this tornado receive?
 Any Future storm chasers in the crowd!?!
CFU
1.
What causes the most damage during a tornado?
2. What is the primary factor responsible for a tornado
touching down?
Hurricane
Damage Caused by Hurricanes
 Most from storm surge
and flooding!!
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.

Comparing & Contrasting
Cyclonic Systems
5 minutes
With your group, complete a VENN DIAGRAM on
hurricanes vs. tornadoes
Each group will be responsible for coming up and writing
one thing for the class consensus Venn Diagram on the
board
at least 2 points comparing the two systems
at least 4 points on their differences. Consider:
- speed
- greatest damage
- location of formation
- time of formation/
predictability
Venn Diagram:
Hurricanes vs. Tornadoes
Comparing and Contrasting
Tornadoes and Hurricanes
Hurricanes
* Form over warm water
* Greatest damage comes from
storm surges and flooding
* Lose speed over land
* Predictable
* Big, but slow
Tornadoes
•Spinning
* Form over land usually
systems
of low
* Greatest damage comes
pressure
from winds
•High
* Sometimes only last
speed
seconds
winds
* Very unpredictable and
fast
