NAMING OF TROPICAL CYCLONES Flashcards
Why are tropical cyclones given names?
To improve communication, tracking, and public awareness.
When did the practice of naming tropical cyclones begin?
In the 1950s, when meteorologists started using female names for storms.
Which organization oversees the naming of tropical cyclones globally?
The World Meteorological Organization (WMO).
How are tropical cyclone names chosen?
Names are selected from pre-approved rotating lists by regional meteorological organizations.
How often are cyclone name lists reused?
Every few years, but names of severe or deadly cyclones are retired.
What happens to the name of a cyclone that causes extreme destruction?
It is retired and replaced with a new name.
Which organization names hurricanes in the Atlantic and Eastern Pacific?
The U.S. National Hurricane Center (NHC).
How are cyclones named in the North Indian Ocean?
The India Meteorological Department (IMD) assigns names from a list contributed by member countries.
What are tropical cyclones called in the Western Pacific?
They are called typhoons, and names are assigned by the Japan Meteorological Agency (JMA).
How are cyclones named in the Southwest Indian Ocean?
The Météo-France La Réunion names them from a regional list.
How many names are in the WMO’s rotating lists for each ocean basin?
Typically 21–26 names per list, rotating every few years.
What happens if all the names in a cyclone list are used in a single season?
Backup lists or the Greek alphabet (used previously) is used.
Why were Greek alphabet names used for hurricanes in 2005 and 2020?
The Atlantic hurricane season had more storms than names available.
Why did the WMO discontinue the use of the Greek alphabet for naming cyclones?
It caused confusion, so an alternate list was created instead.
Which country names the first cyclone of the season in the North Indian Ocean?
The country whose turn is next in the pre-approved list (e.g., India, Bangladesh, Oman, etc.).
What are some famous retired cyclone names?
Katrina (2005), Haiyan (2013), Sandy (2012), and Nargis (2008).
What is the criteria for retiring a cyclone name?
If the storm causes significant destruction and loss of life.
Why do different regions have their own naming lists?
To ensure names are familiar and culturally relevant to local populations.
What happens if a cyclone crosses from one region to another?
It keeps its original name unless it dissipates and reforms.
How does the naming of tropical cyclones help disaster management?
It allows for efficient communication, early warnings, and better coordination of emergency responses.
