Tropical Cyclones

Tropical Cyclones

1. Formation

   • 26.5C
   • Water
   • Warm moist air rises
     • Releases energy
     • Creates low pressure
       • Increases surface winds

2. Movement and Rotation

   • Wind paths deflected by Earth's rotation
   • They move west
     • Easterly winds near the equator
   • Start to curve east
     • Caught in mid-latitude westerlies

3. Intensification and dissipation

   • Intensification
     • Energy from warm water
   • Dissipation
     • Move over land
       • Energy supply is cut off
     • Cooler water

4. Climate change

   • Rising temperatures
     • More water over 26.5C
     • More places suffer from suffer

5. Features and structure

   • Circular
   • Hundreds of km wide
   • last 7-14 days
