The Five FAQs - Cyclone

  1. What is a cyclone?

A cyclone is an extreme weather phenomenon caused by disturbances around a low pressure area over water bodies. Winds spiral around the centre of this low pressure area in a snake-like coil and gather speed. These winds rotate counterclockwise in the northern hemisphere and clockwise in the southern hemisphere.

  1. What are the conditions in which a cyclone is formed?

A warm sea (a temperature in excess of 26 degrees Celsius to a depth of 60 m) with abundant and turbulent transfer of water vapour to the overlying atmosphere by evaporation. Also, atmospheric instability encourages formation of massive vertical cumulus clouds due to convection with condensation of rising air above the ocean surface.


  1. How can one prepare for a cyclone?

Keeping mobile phones charged to ensure connectivity, checking verified sources of information for weather updates, keeping valuables and important documents in water-proof containers, along with preparing an emergency kit helps in preparing for a cyclone. It is also important to secure the house by carrying out repairs and ensuring that sharp objects are not loose. 

  1. What to do if one is outside during a cyclone? 

If one gets stuck outside during a cyclone, they should seek safe shelter as soon as possible but ensure to not enter damaged buildings. They should also watch out for broken electric poles, wires and other sharp objects. 

  1. How can fishermen be safe from a cyclone? 

A fisherman should be updated with the information regarding an impending cyclone from various communication channels such as radio or television. Keep their boats/rafts tied up in a safe place and not venture out in the sea.
