What is a cyclone?

Tropical Cyclone is any large system of winds that circulates about a center of low atmospheric pressure in a counter-clockwise direction north of the Equator and in a clockwise direction to the south.

Cyclone formation:

  • Cyclone is the formation of very low-pressure system with very high-speed winds revolving around it.
  • Factors like wind speed, wind direction, temperature and humidity contribute to the development of cyclones.
  • Before cloud formation, water takes up heat from the atmosphere to change into vapour. When water vapour changes back to liquid form as raindrops, this heat is released to the atmosphere.
  • The heat released to the atmosphere warms the air around. The air tends to rise and causes a drop in pressure. More air rushes to the centre of the storm. This cycle is repeated.
