What Changed
- ▶
BEFORE: Prior to 2018, only eight nations (including India, Bangladesh, and Oman) contributed names for North Indian Ocean cyclones. NOW: The WMO/ESCAP panel includes 13 countries, with Yemen, Iran, Qatar, Saudi Arabia, and the UAE actively contributing to the naming roster (such as 'Ditwah').
- ▶
BEFORE: Tropical cyclones often followed predictable, historical trajectories toward specific coastal landing zones. NOW: Altered climatic variables, like unusually high sea surface temperatures and low vertical wind shear, are increasingly facilitating atypical tracks that parallel coastlines and prolong inland impacts.
- ▶
BEFORE: Cyclones were historically identified using technical coordinates or numbers, which hampered rapid public communication. NOW: Cyclones receive concise, geographically or culturally significant names to rapidly raise public awareness and streamline emergency responses.
