Tropical cyclones(热带旋风) are called typhoons（台风） in Asia, and hurricanes（飓风）in North and South America. These storms go around like a wheel（轮子） turning to the left. They have wind spends of 60 kph or more. They can be very destructive（毁灭性的）.In the United States, the Tropical Prediction Center in Miami, Florida, looks out for hurricanes. When scientists discover a true hurricane, they give it a name. They can use either a man’s or woman’s name. Why should hurricanes have names? The names make it easier forpeople to keep up with information about a hurricane and its dangers.

　 The World Meteorological Organization(WMO) , an international weather group, decides what names will be used. The WMO makes six lists of names, using the English alphabet. Each list is used for one year. When a hurricane happens, it gets the next name on the listfor that year. For example ,the first hurricane of the year might have the name Abel, whilethe second one could Betty. The name lists do not include names beginning with the letters O, U, X, Y, and Z, since there are few names that begin with these letters. Asian countries use a different list. This list has a few personal names, but most of the names are of flowers, animals and trees.
