  2. Why Become A Meteorologist? • Weather Affects Everyone! • Being Able to Predict the Weather Saves Lives!!!

  3. Outline • Clouds • Thunderstorms • Hail/Lightning • Tornadoes • Hurricanes • Tsunamis (Time Permitting)

  4. Types of Clouds

  5. Name That Cloud

  6. Name That Cloud Cumulus

  7. Name That Cloud

  8. Name That Cloud Stratus

  9. Name That Cloud

  10. Name That Cloud Cirrus

  11. Name That Cloud

  12. Name That Cloud Stratus (Fog)

  13. Name That Cloud

  14. Name That Cloud Cumulonimbus

  15. Thunderstorm Formation

  16. How do Clouds Form?

  17. Hail

  18. How does Hail Form? Strong updrafts of warm air and down-drafts of cold air are in a thunderstorm. If a water droplet is picked up by the updrafts...it can be carried well above the freezing level. With temperatures below 32°F...our water droplet freezes. As the frozen droplet begins to fall...carried by cold downdrafts...it may thaw as it moves into warmer air toward the bottom of the thunderstorm But...it may also get picked up again by another updraft...carrying it back into very cold air and re-freezing it. With each trip above and below the freezing level our frozen droplet adds another layer of ice. Finally...our frozen water droplet...with many layers of ice - much like the rings in a tree...falls to the ground - as hail!

  19. What can hail do?

  20. Lightning

  21. How Lightning Forms The connection is made and the protons rush up to meet the electrons. It is at that point that we see lightning and hear thunder. A bolt of lightning heats the air along its path causing it to expand rapidly. Thunder is the sound caused by rapidly expanding air.

  22. Tornadoes What is a tornado? "a violently rotating column of air, pendant from a cumuliform cloud or underneath a cumuliform cloud, and often (but not always) visible as a funnel cloud."

  23. WHERE DO TORNADOES FORM?

  24. WHY DO TORNADOES LIKE THE CENTRAL U.S.?

  25. HOW DO TORNADOES FORM?

  26. Are Winds Faster In the Strongest Hurricane or In the Strongest Tornado?
