A cyclone(Tropical Cyclone to be specific) is formed when the warm temperature of the sea reaches a threshold level and the wind structure is rising. In simple words, cyclones derive their energies from the warm tropical oceans and do not form unless the sea surface temperatures is above 26.5 degrees Celsius. However, once formed, they can persist at lower temperatures and dissipate over land or colder oceans. The originate over the sea and travel about 300-500 kilometers a day.
The IMD scale uses 7 different classifications for systems within the north Indian ocean. Tropical cyclones are amongst the most destructive natural hazards in the world.
