Hurricane-strength storms that make landfall in India are called tropical cyclones. When tropical cyclones form in the southeastern Indian Ocean or the southwestern Pacific Ocean, they are likely to hit such countries as India, Bangladesh and Australia.
Cyclone season in the northern Indian Ocean runs from April to December. Cyclones that form south of the equator rotate in a clockwise direction, which is the opposite of the rotational direction of storms that form north of the equator. This difference is due to the Coriolis effect. Significant cyclones that made landfall in India include Cyclone Phailin in October 2013 and the Odisha cyclone in 1999.
