概括句意：
Hurricanes（龍卷風)
1 Did you know that before 1950,hurricanes had no names? They were simply given numbers.The first names weresimply Alpha,Bravo,Charlie,etc.but in 1953,females names were givenbecause of the unpredictability（不可預知)factor of the storms.In 1979,realizing thesexist（性別歧視的)nature of such names,the listswere expanded to include both men and women.
2 Hurricanes and typhoons（臺風)are the same things.If they formin the Atlantic,we call these strong storms hurricanes,from the West Indianword hurricane,meaning "big wind." And if they are Pacific storms,they are called typhoons from the Chinese taifun,meaning “great wind." Tobe classified as a hurricane,the storm must have maximum winds of at least 75mph.These storms are big,many hundreds of miles in diameter.
3 Hurricanes get their power fromwater vapor as it gives out its stored-up energy.All water vapor gives outheat as it condenses（凝結)from a gaseous state to a liquid state over fixed points on the equator（赤道).To make a hurricane,you musthave extremely wet,warm air,the kind of air that can only be found intropical region.
4 Scientists have determined thatthe heat given out in the process of water condensation can be as high as 95billion kilowatts per hour.In just one day alone,the storm can produce moreenergy than many industrialized nations need in an entire year! The problem isthat we don't know how to make sure such great energy work for us.
5 Predicting the path of ahurricane is one of the most difficult tasks for forecasters.It moves at a typicalspeed of 15 mph.But not always.Some storms may race at twice this speed,thensuddenly stop and remain in the same location for several days.It can bemaddening（發(fā)瘋的)if you live in a coastal area that may behit.
6 The biggest advance in earlydetection is continuous watch from weather satellites.With these,we can seethe storms form and track them fully,from birth to death.While they can stillkill people and destroy property,hurricanes will never surprise any nationagain.
