Tropical Cyclones

===What is a tropical cyclone?=== [1]

  • intense cells of low pressure with a central eye surrounded by a circular wind system
  • storm surges, strong winds
  • unpredictable directions

What Kind of Damage does it do to coral reefs?

  • erosion:
    • destruction and removal of coral
    • removal of surface sand and soil
    • storm ridges [2]
  • biodiversity

Recovery

  • time needed to return to original state
  • greater damage can take anywhere between 5 to 40 years to recover [3]

History of Cyclones

  • Impacts on the Great Barrier Reef
    • Case study: Cyclone Ingrid [4]
      • intensity
      • damages
    • Case study: Cyclone Yasi [5]
      • intensity
      • damages

How to Protect against Tropical Cyclones

  • Marine protected areas
    • NTAs provide protection and act as sources of recovery after natural disasters
