Why the cyclones are named as katrina, nargis etc? What is the system of nomenclature?

"The national weather services of countries that get hurricanes, tropical cyclones or typhoons submit lists of names to the World Meteorological Organisation which approves them. The names are supposed to reflect the ethnic make-up of the country involved. The lists of names are published and each warning centre has its own list. If a storm forms in their area, they get to name it.

Most countries submit names of people, alternating male and female. Thirteen countries affected by typhoons have combined names for their list but they also use names of flowers and other non-human names. The first country to use male and female names alternating was Australia in 1975. By 1979 the rest of the world had followed suit. ..."

Huuricanes, typhoons, and tropical cyclones are all the same kind of storm, but are called by these designations according to their location. In the Atlantic, North Central Pacific, and the Northeast Pacific, they are called hurricanes. Atlantic and NE Pacific hurricanes are named alternating male and female names starting with the first letter of the alphabet until they reach the end of the alphabet if they have that many hurricanes. They used to use only female names, but changed to alternating male and female The letters Q, U, X, Y, and Z are omitted in naming Atlantic hurricanes. Only Q and U are omitted in the Northeastern Pacific. If they have more after using all of the alphabet except the omitted letters, they go to the Greek alphabet, eg: Alpha, Beta, etc. In the North Central Pacific, hurricanes are named by the Central Pacific Hurricane Center in Honolulu, using Hawaiian names sequentially. In the NW Pacific names are assigned by the World Meteorological Organization Typhoon Committee. Two names are submitted by each of the 14 countries on the Commitee.

The Australian Bureau of Meteorology names typhoons on the North, West, and East sides of Australia alphabetically, alternating male and female names, but they do not alternate the gender of the starting name yearly. They continue sequentially from the last gender used the previous year.

It gets even more complicated when you get into the various Southern pacific typhoon (or cyclone names), but this info is from Wikipedia under Tropical Cyclone Naming, if you are interested in the rest of it.

Typhoons are

In Spanish the masculine 'el mar' is the excellent translation of the sea. Many sailors who understand the sea prefer to apply the grammatically incorrect female 'l. a. mar'. the sea could be considered as a perpetual masculine foe. A worth opponent to be conquered or mastered. the sea is additionally considered as a eye-catching source of nurturing, giving boundless wealth. yet like a girl, she has moods. at times its calm and eye-catching. At different cases it is gray and hassle. on social gathering the temper is a black deadly fury like a typhoon. for that reason hurricanes used to have purely female names. these days the politically superb brigade (people who would be first against the wall while the revolution comes) has ruined an historic admire for the sea via insisting names for hurricanes be the two lady and male. Katrina, Rita, Nargis get matched against Andrew, Floyd, and Mitch

i think it goes alphabetically and by male/female.
