  1. Atlantic Hurricanes By: Nichole Quihuis Grade 7

  2. A Hurricane is… • A rotating cyclone of thunder storms with a defined central eye • Sustained wind speeds of at least 74 mph • They form generally in the tropic regions • Fueled by warm sea surface temperatures and low atmospheric pressure

  3. Formation of a Hurricane • Begins with low pressure off the coast of Africa • Strong westerly winds • Strong evaporation due to warm sea surface temperatures • Initial cluster of thunderstorms (Tropical Depression) • Thunderstorms form more organized circular bands around the central eye

  4. Hurricane Season • Summer months into early fall (June-September) • Possible winter hurricanes if conditions are right • Increased sea surface temperatures • Stronger evaporation • Associated with a defined shift in westerly winds in the Northern Hemisphere

  5. Hurricane Strength • Categories • 5 Categories with 1 being the weakest • Category 1 is 74-95 mph • Category 2 is 96-110 mph • Category 3 is 111-130 mph • Category 4 is 131-155 mph • Category 5 is 156 mph or greater

  6. FUN FACT!! • The total amount of energy released by a hurricane (rainfall, heat radiation, and wind) is equivalent to 200 times the world-wide electrical generating capacity!!!!!! • WOW!!!!!!!!!!!!!

  7. Damage Effects • Most of the damage comes from storm surge • Wind • Flooding from rainfall • A lot of communication infrastructure damage
