Naming cyclones

Date: 10 May 2022 Tags: Geography & Environment

Issue

Indian Meteorological Department (IMD) has named the cyclonic depression over South Andaman Sea as Asani.

 

Background

The cyclone is the first one of the year and the name was suggested by Sri Lanka, which means wrath in Sinhala.

 

Need for naming

  • Cyclones are given names to avoid confusion, facilitating disaster risk awareness, management, and mitigation.

  • Multiple storms can be formed in a particular geographical location or around the globe. Therefore, each tropical storm is given a name to avoid any confusion.

  • Naming cyclones are less subject to error than the older and more problematic latitude-longitude identification methods.

 

Naming authority

  • There are five regional Tropical Cyclone Warning Centres around the world who issue advisories and name cyclones.

  • The IMD names cyclone which forms over northern Indian Ocean after reaching a sustained surface wind speed of 62 kmph or more.

 

Criteria for naming

  • Suggested names by the countries should be neutral to gender, politics, religious beliefs and cultures.

  • The name of cyclone can have a maximum of eight letters. The same name will not be used again.

 

Countries in the region

India, Bangladesh, Iran, Maldives, Myanmar, Oman, Pakistan, Qatar, Saudi Arabia, Sri Lanka, Thailand, United Arab Emirates and Yemen.
