  • Transcript

    • 1. Hurricanes
    • 2. What is a hurricane? Hurricanes are tropical cyclones. They form in the southern Atlantic Ocean, Caribbean, Gulf of Mexico, and eastern Pacific Ocean. Their winds spiral outward in a counterclockwise, circulation pattern.
    • 3. What conditions must exist for ahurricane to form? Low to medium winds blowing in the same direction 5–30 degrees north of the equator in the ocean Ocean surface temperature of greater than 80 F that extends down to about 150 feet deep (50 m) Lower atmosphere must be moist
    • 4. How do hurricanes form? The air mass above the tropical waters takes on the temperature and humidity of the water beneath it. Incoming winds force the air upward. The warm, moist air rises, forming water vapor and clouds. Above the storm, the winds flow outward. Outside winds blow inward, and the cycle repeats.
    • 5. How do hurricanes move? Hurricanes turn to the right, away from the equator, because of the Coriolis Effect caused by Earth’s rotation. You will learn about this phenomenon later in the lesson.
    • 6. Where does the energy for ahurricane originate? The Sun heats the oceans. Warm air rises, and as it cools, it releases energy, fueling the hurricane.
    • 7. Why don’t hurricanes form inhigher latitudes? The temperature of the oceans is not warm enough. The distance is too far from the equator.
    • 8. Hurricane Katrina
    • 9. Reflective QuestionHow do oceans play a role in thedevelopment of weather systems includinghurricanes?
