Tropical cyclones are the worst natural hazards in the tropics. They are large revolving vertices in the atmosphere extending horizontally from 150-1000kms and vertically from the surface from 12-14kms. These are intense low pressure areas. They generally move 300-5000kms per day over the ocean. While moving over the ocean, they pick up energy from the warm water of the ocean and some of them grow into a devastating intensity.
The main dangers from cyclones are very strong winds, rains and high strong tides. Most of the casualties are caused by coastal inundation by storm tides. This is often followed by heavy rainfall and floods. Storms cause the greatest destruction.
Although one cannot control cyclones, the effect of cyclones can be mitigated through effective and efficient mitigation policies and strategies. A brief description of the same is given below:
