Model Answer
0 min readIntroduction
Cyclones, powerful weather systems, are named to facilitate communication and avoid confusion when multiple storms occur. The recent cyclone 'Phailin' (2013) which impacted the east coast of India, exemplifies this practice. The naming of tropical cyclones isn’t random; it follows a systematic approach coordinated globally by the World Meteorological Organization (WMO) through its regional specialized meteorological centres (RSMCs) and regional bodies. This system aims to reduce ambiguity and enhance public awareness regarding impending threats.
Global Naming Conventions
The WMO coordinates the naming of tropical cyclones across different ocean basins. Each of the six Regional Specialized Meteorological Centres (RSMCs) – New Delhi (North Indian Ocean), Tokyo (North-West Pacific), Honolulu (Central North Pacific), Miami (Atlantic & Eastern North Pacific), Wellington (South-West Pacific), and La Reunion (South Indian Ocean) – maintains rotating lists of names.
Regional Bodies & Lists
- North Indian Ocean: WMO/ESCAP Panel on Tropical Cyclones – Bangladesh, India, Maldives, Myanmar, Pakistan, Sri Lanka, Thailand.
- North-West Pacific: Typhoon Committee – 14 member countries.
- Atlantic & Eastern North Pacific: Names are maintained and updated by the WMO.
Naming Process
Each region has pre-determined lists of names, typically alphabetical, and alternates between male and female names. Once a cyclone reaches a certain intensity (wind speed), it’s assigned the next name on the list. If a cyclone is particularly deadly or costly, its name is retired and replaced with another. The lists are revised periodically.
Conclusion
In conclusion, the naming of tropical cyclones is a globally coordinated effort led by the WMO, utilizing rotating lists maintained by regional bodies. This system enhances communication, preparedness, and public awareness, ultimately contributing to disaster risk reduction. The process ensures clarity and avoids confusion during simultaneous storm events, as exemplified by cyclones like 'Phailin'.
