1. Objective: Describe and analyze the formation of severe weather.

2. 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

3. Math EOC Review Problem: How can we make these reviews more helpful?

4. Agenda Do Now/Math EOC Review Air Masses & Air Fronts Review Air Mass & Front Foldable Hurricane Katrina, 5 years later Tornado & Hurricane Search TORNADO & HURRICANE VIDEO CLIPS Venn Diagram Exit Ticket

5. Objective SWBAT describe and analyze the factors leading up to the development of severe cyclonic systems

6. Announcements: Unit 7 Test: Friday, May 11 th Unit 8: Astronomy (Last Unit!!!) Tuesday: Substitute + Plan Come in during lunch or after school to finish your test corrections!

7. Quote of the Day “Peace is not merely the absence of tension, it is the presence of justice” -Martin Luther King Jr.

8. HURRICANE KATRINA… 5 years later http://projects.usatoday.com/news/katrina/#/prologu e/the-storm/the-storm

11. 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

12. CYCLON IC 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? Tornad oes Hurrica nes

13. What is a Tornado?

14. 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

15. Damage Caused by Tornadoes Extremely high winds can tear buildings apart, slip cars, and even suck the water out of a riverbed

16. Tornado in Joplin, Missouri May 2011

17. 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!?!

18. CFU 1. What causes the most damage during a tornado? 2. What is the primary factor responsible for a tornado touching down?

19. Hurricane

20. Damage Caused by Hurricanes Most from storm surge and flooding!!

21. 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.

22. Raging Planet: Hurricanes 10:35-17:48 http://www.dailymotion.com/video/xa95p7_raging- planet-tornado-2009-part- 1_tech?ralg=thefilter#from=playrelon Answer the questions and fill in the blanks on the worksheet provided while you watch

23. CFU 1. What produces the most damage during a hurricane? 2. How is a hurricane formed? 3. What gives a hurricane its energy? 4. What happens when a hurricane hits land?

25. Comparing & Contrasting Cyclonic Systems5 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

26. Venn Diagram: Hurricanes vs. Tornadoes

27. 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 * Form over land usually * Greatest damage comes from winds * Sometimes only last seconds * Very unpredictable and fast Spinning systems of low pressure High speed winds
