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

Hurricane and Tornado Search Textbook page Quietly in your seat, take 15 minutes to complete your graphic organizer As you go, consider similarities and differences between the 2 storms

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

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 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.

Raging Planet: Hurricanes 10:35-17:48 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

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?

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

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 * 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
