Geog tropical cyclones

• Intense


  CTF wind
• TROPICAL CYCLONES


  Big, circular, low-pressure systems that develop over warm tropical oceans where the sea temperature is over 27°C in late summer and early autumn
• Tropical cyclones


  • Storm diameters are generally 600km in extent ie smaller than mid-latitude cyclones in diameter
  • Occur in the late summer and early autumn
  • Can travel up to 200km a day
  • Pressure gradient is much steeper in a tropical cyclone
• Names of tropical cyclones in different places

  • Indian Ocean: Tropical cyclones
  • Japan: Typhoons
  • Australia: Willy
  • Americas: Hurricane
• First letter of cyclone name

• Tropical cyclones


  • Are accompanied by inspiralling winds with speeds of up to 300km/hour
  • There are no fronts, and the isobars form closely spaced concentric circles
• Flooding can result from intense rainfall and storm surges
• Areas where tropical cyclones develop

  • NORTH
  • SOUTH
  • FACING
  • ATLANTE OCEA
  • NOWN OGLAN
• Tropical cyclones form between latitudes 5" and 25° N and 5 of the equator
• Tropical cyclones form in tropical latitudes and driven by easterlies/trade winds
