Hurricanes do not form at the equator because Description sea-surface temperatures are too low Course Schedule winds in the upper troposphere are always too strong Grading the coriolis effect is zero Learning thunderstorms are infrequent Objectives Photographs 2. A location which is not likely to experience a Practice hurricane is Questions New England Special Notice Florida Student Louisiana Responsibilities Oregon Access to Online 3. Hurricanes Daily Weather sometimes develop from waves on the polar front Summary and are cold-core cyclones Learning have warm fronts but not cold fronts Activities develop in a uniform mass of very warm and humid air National Weather 4. The horizontal pressure gradient in a hurricane is Service - Green _____ that in a typical extratropical cyclone. Bay greater than about the same as Home less than 5. In the eye of a hurricane, the sky may be almost cloud-free air subsides and warms adiabatically winds are light All of the above are correct 6. The eye wall of a hurricane consists of a ring of ______ clouds. stratus cirrostratus cumulonimbus nimbostratus 7. Hurricanes form over ocean water at a temperature of at least ________ degrees Celsius to a depth of 60 m (200 ft). 10 15.5 26.5 30 8. The minimum latitude where the Coriolis effect can sustain a hurricane circulation is about _______ degrees. 60 23.5 10 4 9. Hurricanes do not form off either South American coast primarily because winds aloft are too strong sea-surface temperatures are too low the Coriolis effect is too weak None of the above is correct 10. The most hurricane-prone region of the United States is New England Long Island, New York Coastal North Carolina the Florida Keys 11. Most Atlantic hurricanes develop in spring winter and early spring late summer and autumn summer 12. Hurricane damage is caused by stong winds associated tornadoes storm surge All of the above are correct 13. The Saffir-Simpson Scale is based on central air pressure sustained wind speed storm surge potential All of the above are correct 14. As a hurricane or tropical storm tracks well inland, winds usually diminish rapidly rains quickly taper off property damage is due more and more to strong winds and less and less to flooding None of the above is correct 15. As a hurricane travels from sea to land, its surface winds shift toward ______ pressure. high low 16. Potentially the most devastating aspect of a hurricane that strikes low-lying coastal areas is (are) torrential rains strong winds a storm surge lightning from the eye wall 17. The most intense hurricanes rate _______ on the Saffir-Simpson Scale. 1 2 4 5 18. The initial stage in the life cycle of a hurricane: tropical depression tropical disturbance tropical storm typhoon 19. The criterion for upgrading a tropical storm to a hurricane: central air pressure diameter of the eye sustained wind speed storm surge potential 20.
