　　Hurricanes 　　2. Hurricanes and typhoons are the same things. If they form in the Atlantic, we call these strong storms hurricanes, from the West Indian word hurricane, meaning big wind. And if they are Pacific storms, they are called typhoons from the Chinese taifun, meaning great wind. To be classified as a hurricane, the storm must have maximum winds of at least 75 mph. These storms are big, many hundreds of miles in diameter. 　　4. Scientists have determined that the heat given out in the process of water condensation can be as high as 95 billion kilowatts per hour. In just one day alone, the storm can produce more energy than many industrialized nations need in an entire year! The problem is that we dont know how to make such great energy work for us. 　　6. The biggest advance in early detection is continuous watch from weather satellites. With these, we can see the storms form and track them fully, from birth to death. While they can still kill people and destroy property, hurricanes will never surprise any nation again.
