Weather scientists call hurricanes by names to make clear which storm they are talking about. An Australian weather scientist began giving women’s names to storms before the end of the nineteenth century. Weather scientists used the names of their girlfriends or wives for storms during World War Two. (33) The United States weather service started officially using women’s names for storms in nineteen fifty-three. In nineteen seventy-eight, it began including men’s names as well.
    (34) Today, scientists make up lists of names years in advance, They agree on them at meetings of the concerned organization. The lists include both American and international names.
    The United States National Hurricane Center near Miami, Florida, watches for the development of storms. It gives a name to each one that reaches a wind speed of sixty-two kilometers an hour. A different list of names is used each year. The first name begins with the letter "A". The second begins with "B" and so on. The same list will not be used again for at least six years. The names of storms that have caused extremely severe damage may be retired at the request of the country that was affected. That name will not be used again for at least ten years. (35) This is done to avoid legal problems or confusion. It may be reasonable that the United States asks that the name Katrina be retired.
