WEATHER PATTERNS Lesson 5 Key Question What are the atmospheric conditions associated with a tornado?
Student ObjectiveFriday, November 7, 2014 • OBJECTIVE: SWBAT describe the atmospheric conditions associated with tornadoes. • Homework: Start a Venn diagram on thunderstorms & tornadoes.
Warm Up • Where does lightning usually strike? How can you stay safe during a thunderstorm? • Where is a safe place to hide during a tornado?
NOAA Today’s Activities • Review warm-up • Thunder demonstration • Finish Lightning and Thunderstorms W/S • “Tornado in a Bottle” Lab
Lightning and Thunderstorms W/S • CyberEd activity • Thunderstorm details • http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/svr/type/home.rxml
Lightning • 30,000 °C - hotter than the sun • May cause fires • Severe electrical shock • Lightning strikes on sand can produce fulgurites
Speed of Light v. Speed of Sound • Sound travels at 343 m/s(5 miles per second) • Light travels at 300,000,000 m/s(186,000 miles per second)
Speed of Light v. Speed of Sound Sound Light
Mid-Point Conclusion • What are the two major air currents in a mature thunderstorm? • Why can you see lightning before you hear the thunder it produces?
Tornado Frequency • How does the number of tornadoes relate to the time of year? Why would this be the case? http://www.spc.noaa.gov/archive/tornadoes/tornmavg.gif
Tornado Internet Activity • Use these websites to complete the worksheet: • http://www.nssl.noaa.gov/NWSTornado/ • http://www.nssl.noaa.gov/noaastory/booklo.html • http://www.usatoday.com/weather/wconvcap.htm
Conclusion • How do the atmospheric conditions of a thunderstorm contribute to the development of a tornado?
