Cyclone Dana, a tropical cyclone that formed in the Indian Ocean, is expected to cause heavy rains in Odisha in the coming days. But have you ever wondered how cyclones get their names?
The Naming Process
The World Meteorological Organization (WMO) is responsible for maintaining the list of names for tropical cyclones globally. The WMO uses a predetermined list of names, which are assigned alphabetically and rotate every six years.

The Story Behind “Dana”
The name “Dana” was contributed by Saudi Arabia, one of the 14 countries participating in the WMO’s tropical cyclone naming system for the North Indian Ocean. The name “Dana” is derived from Arabic, meaning “generosity” or “bounty.”
Regional Significance
Naming cyclones after regional words or names helps raise awareness and promotes cultural exchange among countries affected by these storms. It also makes communication and warning systems more effective.
Recent cyclones in the region have been named after contributions from various countries, including:
– Cyclone Tauktae (named by Myanmar, meaning “gecko”)
– Cyclone Nivar (named by Iran, meaning “light” or “breeze”)
– Cyclone Amphan (named by Thailand, meaning “sky”)
