Rising Cyclone Trends in the Arabian Sea and Bay of Bengal: A Climate Change Impact

• Cyclones form over warm waters due to low-pressure systems. 
• The Bay of Bengal is slightly warmer. Because of climate change, the Arabian Sea side is also getting warmer, and as a result, the number of cyclones in the Arabian Sea is showing an increasing trend in the recent trend.

Global Cyclone Naming Protocol: Collaborative Practices and Regional Roles

• Rotational Basis: Cyclones are named by countries on a rotational basis.
• Regional Meteorological Centers: Worldwide, six specialized regional meteorological centers (RSMCs) and five regional Tropical Cyclone Warning Centres (TCWCs) are mandated for issuing advisories and naming tropical cyclones.
• IMD’s Role: The Indian Meteorological Department (IMD) is one of the RSMCs providing advisories and naming for the north Indian Ocean, including the Bay of Bengal and the Arabian Sea.
• Member Countries: IMD serves 13 member countries under the WMO/Economic and Social Commission for Asia-Pacific (ESCAP) Panel, including Bangladesh, India, Iran, Maldives, Myanmar, Oman, Pakistan, Qatar, Saudi Arabia, Sri Lanka, Thailand, United Arab Emirates, and Yemen.

Evolution of Cyclone Naming Process: Establishing Protocols and Collaborative Lists

• Agreement: The WMO/ESCAP Panel on Tropical Cyclones agreed to assign names to cyclones in the region in 2000, with naming starting in September 2004.
• List of 169 Names: IMD released a list of 169 cyclone names in 2020, with 13 suggestions from each of the 13 member countries.

Guiding Principles for Cyclone Naming Process: Ensuring Neutrality and Sensitivity

• Neutrality: Proposed names should neutralize politics, religious beliefs, cultures, and gender.
