  1. WEATHER PATTERNS Lesson 4 Key Question How does a thunderstorm develop?

  2. Student ObjectiveFriday, August 29, 2014 • OBJECTIVE: SWBAT explain the formation of thunderstorms. • Homework: Describe three different ways to demonstrate thunder.

  3. Before Your Warm-Up • QUIZ – but not a quiz? • This will not count towards your grade • Help Mr. Shelton measure how much you learn

  4. Warm Up • How can you tell when a thunderstorm is coming your way? • If you went outside 15 minutes after a thunderstorm passed by, what evidence would you see that the storm had been there?

  5. Today’s Activities • Review warm-up • Life cycle of a thunderstorm • Lightning and Thunderstorm W/S • CyberEd – Weather and Atmospheric Processes – Weather #14b • Thunderstorm information on internet

  6. Life Cycle of a Thunderstorm • Warm, humid air rises in an updraft

  7. Life Cycle of a Thunderstorm • Updraft continues higher • Cumulonimbus cloud • Hail may develop • Cold downdraft begins

  8. Life Cycle of a Thunderstorm • Cold downdraft eventually makes the storm dissipate

  9. Life Cycle of a Thunderstorm

  10. Lightning Evidence • 30,000 °C - hotter than the sun • May cause fires • Severe electrical shock • Lightning strikes on sand can produce fulgurites

  11. Activities • Lightning and Thunderstorms W/S • CyberEd activity • Thunderstorm details • http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/svr/type/home.rxml

  12. Lightning Formation Diagram

  13. Lightning Strikes • Look at these maps showing the locations of lighting strikes: • http://edot.lanl.gov/event_animations/199906_us_4.gif (June 1999) • http://www.weather.com/maps/activity/golf/uslightningstrikes_large_animated.html (today) • Is there a pattern to where lightning occurs? Why would some locations have more lightning than others?

  14. Conclusions • Why do we mostly experience thunderstorms in the spring & summer?
