CYCLONES

• Tropical cyclones in the warm oceans are formed to heat and moisture. Sea surface temperature should be above 26⁰C. Cyclones move like a spin (120-400 km/hr) with a diameter of 100-1500 km.
• The following are the examples of types of cyclones:
  • Hurricane in the Atlantic, Caribbean and North East Pacific areas.
  • Typhoons in Western Pacific areas.
  • Cyclone in the Indian Ocean.
  • Willy Willies in the sea around Australia.
  • Cyclones occur more in the Bay of Bengal than Arabian Sea.

Management

• It is not possible to stop cyclones. But we can follow certain measures to escape from their devastation. The measures are as follows:
  • Planting of trees along coastal belts.
  • Construction of dams and wind breaks.
  • Installation of wide roads for the people to evacuate quickly in emergencies.
  • Installation of better working system.
  • Construction of proper drainage.
  • Disaster prediction i.e., announcement of cyclone warning to people would help in minimizing the impact.
