Consider the following statements:

1. The centre of tropical cyclone is colder than its surroundings.
2. Hurricane and typhoon are tropical storms.
3. Tropical cyclones are areas of low atmospheric pressure in the Earth's atmosphere.

Which of the above statements is/are correct?

Option 1 is wrong. At any given altitude, except close to the surface, where water temperature controls air temperature, the environment inside the cyclone is warmer than its outer surroundings. Option 2 is wrong as hurricane, typhoon and tropical storms are tropical cyclones with tropical storm not usually having an eye as compared to the other two. Option 3 is correct as tropical cyclone develop over large bodies of warm water, i.e. the atmospheric pressure is low and loses the strength if they move over land due to increased surface friction and loss of the warm ocean as an energy source. Cyclone Thane that recently hit India is a tropical cyclone.
