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 sentences2. Think Back: What type of air pressure
system is associated with high precipitation and stormy weather?

ObjectiveSWBAT describe and analyze the
factors leading up to the development of severe cyclonic systems
RemindersTutoring Monday/Friday/most Tuesdays for remediation, test re-takes

Hurricane and Tornado SearchTextbook page. 573-577Quietly in your seat, take 15 minutes to
complete your graphic organizerAs you go, consider similarities and
differences between the 2 storms
CYCLONIC SYSTEM
What is it? How does the storm develop?
How often does this storm occur?
What is the intensity ranking?
Associated with High or Low Pressure?
Tornadoes
Hurricanes
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 TornadoesExtremely high winds can tear buildings
apart, slip cars, and even suck the water out of a riverbed

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 HurricanesMost from storm
surge and flooding!!
FAST FACTThe 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 minutesWith your group, complete a VENN DIAGRAM on
hurricanes vs. tornadoesEach 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 systemsat least 4 points on their differences. Consider:
- speed - greatest damage- location of formation - time of formation/ predictability
