  1. Do Now How do you think a tornado and hurricane differs? Think beyond the fact that one occurs over the ocean and another occurs over land.

  2. Announcements • Quiz on Friday covering atmosphere chemical composition, layers of the atmosphere, fronts, air pressure, and the storms we’ve covered so far. • You’ll do great! • It’ll take us about 25 minutes tops. • Progress reports today

  3. Agenda • Finish presentations from yesterday • INM Hurricanes • Venn Diagram

  4. Hurricanes • Brain pop movie • http://www.brainpop.com/science/weather/hurricanes/

  5. Let’s Prepare for a Hurricane!

  6. What's a hurricane? • A hurricaneis a very destructive and dangerous storm. • Hurricanesare filled with rain, strong winds, lightning, thunder, hail and tornadoes. • In these storms, when the winds range from 35 to 54 miles an hour, it is called a tropical depression. • When the winds are from 55 to 74 miles an hour then it is called a tropical storm. When it reaches 75 miles an hour, it is called a hurricane.

  7. How do they measure hurricanes?

  8. What is the “eye” of the hurricane? • Eye of the Hurricane: The eye is the calm center of a hurricane. In the middle of the storm, things may seem calm, but you may be in the middle of the storm. Listen to the radio to find out when the storm has really passed.

  9. What does evacuate mean? • Evacuate: You and your family may be asked to leave your home. You can return after your town or state leaders say you can return.

  10. What does flooding mean? • Floods: Flooding occurs when water rises. More people are killed by floods during a hurricane than by any other hazard. Tidal surges push water in hurricanes and can cause flooding.

  11. What is a storm surge? • Storm surge: Storm surge is a massive dome of water, that sweeps across the coast near the area where the eye of the hurricane comes makes landfall. The stronger the hurricane the higher the storm surge. For those living along the coast, storm surge is one of the most dangerous parts of a hurricane. Here are examples of a storm surge flooding a town.

  12. What is a hurricane watch & warning? • Hurricane Watch: A hurricaneis possible within 36 hours. Listen closely to the radio and television for more information. It is very important for your parents to listen for the hurricane updates. • Hurricane Warning: A hurricaneis expected within 24 hours. You may be told to evacuate. You and your family should begin preparations to evacuate.

  13. Venn Diagram • Compare and contrast hurricanes and tornadoes using a Venn Diagram. • Occurs in advance of a cold front • Occurs in the warmest waters in oceans • Caused by winds colliding
