In which year did the naming of tropical cyclones in the north Indian Ocean begin?
- A.1999
- B.2004
- C.2013
- D.2018
Correct answer
Explanation
The correct answer is B, 2004. The eight countries of the WMO and ESCAP Panel on Tropical Cyclones agreed on a list of names for this basin and began using them in 2004, long after the Atlantic, where naming had been practice for decades. Option A, 1999, is remembered for the Odisha super cyclone that struck Paradip, a storm that carried no name precisely because the system did not yet exist. Option C, 2013, is the year of cyclone Phailin, a name contributed by Thailand, and so falls inside the naming era rather than at its start. Option D, 2018, is the year five more countries, Iran, Qatar, Saudi Arabia, the United Arab Emirates and Yemen, joined the panel and raised its strength to thirteen, after which the longer list of 169 names was prepared and released in 2020. Keep 2004 for the start and 2018 for the enlargement.
