About Cyclone Dana

The Naming Process

• The names of tropical cyclones are managed by the World Meteorological Organization (WMO), which ensures that a predetermined list of names is used for each storm. 
• These names are rotated every six years and follow an alphabetical order. The process is designed to help improve communication, raise awareness, and make it easier for people to follow the path and impact of these storms.

World Meteorological Organization (WMO)

The World Meteorological Organization (WMO) is a specialized agency of the United Nations. The WMO was established by the Convention of the World Meteorological Organization, signed 11 October 1947 and ratified on 23 March 1950. The WMO is made up of 193 countries and territories. WMO is Headquartered in Geneva, Switzerland. WMO is governed by the World Meteorological Congress, composed of member states, which meets every four years to set policies and priorities.

The Origin of '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 word "Dana" is derived from Arabic, meaning "generosity" or "bounty." 
• It reflects the region's cultural significance, and naming cyclones after local terms encourages awareness and raises cultural exchange among nations affected by these storms.
• This is not the first time a cyclone has been named after a regional term. 

Some notable examples include: 

• Cyclone Tauktae (named by Myanmar, meaning "gecko") 
• Cyclone Nivar (named by Iran, meaning "light" or "breeze") 
• Cyclone Amphan (named by Thailand, meaning "sky") 

These names help make the storms more relatable and create a sense of regional identity in the global effort to track and predict their paths.
