About Cyclones

  • The National Disaster Management Authority (NDMA) classifies cyclones into two categories: extratropical cyclones and tropical cyclones.
  • A cyclone is a large-scale system of air rotating around the center of a low-pressure area, characterized by inward spiraling winds that rotate anticlockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
  • Extratropical cyclones, also known as mid-latitude cyclones, occur outside the tropics and have cold air at their core. They derive energy from the interaction of cold and warm air masses and always have one or more fronts connected to them.
  • Tropical cyclones develop in the regions between the Tropics of Capricorn and Cancer and are the most devastating storms on Earth. They derive energy from the latent heat released when water vapor condenses into liquid water. Unlike extratropical cyclones, tropical cyclones do not have associated warm fronts or cold fronts.
  • Tropical cyclones have different names depending on their location and strength, such as hurricanes in the Caribbean Sea, the Gulf of Mexico, the North Atlantic Ocean, and the eastern and central North Pacific Ocean, while in the western North Pacific, they are called typhoons.
