Grade 7

a hurricane is
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
formation of a hurricane
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
hurricane season
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
hurricane strength
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
fun fact
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!!!!!!!!!!!!!
damage effects
Damage Effects
  • Most of the damage comes from

storm surge

  • Wind
  • Flooding from rainfall
  • A lot of communication infrastructure damage
