HOW KATRINA GOT ITS NAME

Hurricanes names are chosen from a list selected by the World Meteorological Organization. The Atlantic is assigned six lists of names, with one list used each year. Every sixth year, the first list begins again. Each name on the list starts with a different letter, for example, the name of the very first hurricane of the season starts with the letter A, the next starts with the letter B, and so on. The letters "Q", "U", "X", "Y" and "Z", however, are not used.

Often when an unusually destructive hurricane hits, that hurricane's name is retired and never used again. Since 1954, forty names have been retired. In 1996 Hurricane Luis was retired. Naming hurricanes began hundreds of years ago. But only recently they began to name it after women. It was during World War II the forecasters and meteorologists began using female names in identifying the storms the storms. In 1953, the US weather service officially adopted the idea and created a new phonetic alphabet (international) of women’s name from A to W. 

It is much easier to name a hurricane than trying to remember storms by its longitude and latitude. It is also easier when you have more than one hurricane you are tracking. There are lists of name that can be rotated. Usually, the six lists of names for tropical storms and hurricanes repeat every six years. 

However, if there is an unusually large or damaging hurricane, the name is retired by the World Meteorological Organization’s hurricane committee because using it again could be considered insensitive. The hurricane name is then retired not used for at least ten years. So the name Katrina would never be used again or it has to wait for another 10 years to be used again.

Here are part of the list of hurricane name,
