For the tornado that struck Moore, Oklahoma on May 20, 2013, and earlier events in this city’s history in May 3, 1999, May 2003, and currently in May 2013, describe the Fuji ta scale ranking of these three events, and the losses that were incurred as a result of the tornadoes on these occasions, as well as the tell-tale radar images in each of these three events 
3. In April 2011, an outbreak of tornadoes occurred on April 14. Describe this outbreak of tornadoes, how many states were affected, how many hours did it go on and last, how many states were affected, and how many people lost their lives, and rank this in terms of US tornado history 

4. What is La Niña, and what role does it play in the formation of tornadoes in tornado alley? “DeadliestTornadoes” links La Niña with three major episodes of tornadoes in the United States, 1974, 2002, and 2011. Explain what happened in each of these years and cite some statistics as to how many tornadoes occurred, how many states were involved, what damages took place based on what you can find in the NOVA videos, your textbook, or online sources. 

5. in “Deadliest Tornadoes” an outbreak is described that took place on April 25, 2011. Describe this outbreak of tornadoes, what weather service specialists observed on their radar, and some details on the scale of this outbreak, the states that were affected, the numbers of tornadoes produced, and the ranking of this outbreak with respect to US history 
6. In “Oklahoma’s deadliest tornadoes,” Howard Bluestein talks about the improvement to Doppler radar called dual polarization radar. What can this radar system see, and how does that help us in warning people of an oncoming tornado with greater lead time? 

7. In “Oklahoma’s deadliest tornadoes,” scientists discuss what set up the tornado that hit Joplin, Missouri. Describe the events that led to the formation of the tornado that hit Joplin, discuss the scale of its impacts, it’s ranking on the Fuji ta scale, and the type of damage that it did to the city of Joplin, as well as why the disaster site clearly indicates the ranking given to this tornado. 

8. Why is it that the F5 that hit Moore, Oklahoma on May 20, 2013 killed only 24 people, where as a similar event impacting Joplin Missouri the city on May 22, 2011 as suggested in the video “Oklahoma’s deadliest tornadoes”

9. Explain why global climate change, warming of earth’s atmosphere, could possibly set up conditions to make tornadoes more frequent and more powerful, as well as eventually resulting in the kinds of tornadic events we are currently seeing in the southern Plains occurring in the Great Lakes region 
10. How can we best protect people in the future if we cannot prevent tornadoes from happening?
