摘要:Storms can result when the air temperature in one area is different from that of another.Warmer air rises and cooler air falls.These movements create a difference in the pressure of the atmosphere. If the pressure changes over a large area.winds start to blow in a huge circle.High­pressure air is pulled into a low­pressure center. Severe ocean storms happen less often in the southern hemisphere.There the season of greatest activity is between December and March. South of the equator.the winds flow in the same direction as the hands on a clock.North of the equator.they flow counter­clockwise. This is because as Earth turns.air is pulled to the right in the northern hemisphere.In the southern hemisphere.air is pulled to the left. Storms can get stronger and stronger as they move over warm ocean waters.The strongest.fastest winds of a hurricane are found in the eye­wall.This is the area that surrounds the center.or eye.of the storm.The eye itself is calm by comparison.with light winds and clear skies. Winds in severe ocean storms can reach speeds of more than two hundred and fifty kilometers an hour.Up to fifty centimeters of rain can fall.Some storms have produced more than one hundred and fifty centimeters of rain. These storms also cause high waves and ocean surges.A surge is a continuous movement of water that may reach six meters or more.The water smashes across low coastal areas.Surges are commonly responsible for about ninety percent of all deaths from ocean storms. Weather scientists use computers to create models that show where a storm might go.Models combine information such as temperatures.wind speed.atmospheric pressure and the amount of water in the atmosphere. Scientists collect the information with satellites.weather balloons and devices floating in the world’s oceans.They also collect information from ships and passenger flights and from planes that fly into and around storms.The crews drop instruments on parachutes to record temperature.pressure.wind speed and other conditions. In July.ten scientists released a statement about what they called the main hurricane problem facing the United States.They warned that the problem is development in coastal areas at risk from hurricanes. They called on government leaders not to support policies that have increased the density of population and wealth in these areas.Their message was that building in risky coastal areas only increases the amount of destruction when a hurricane strikes.1.Under what conditions do storms result?(no more than 13 words)

A businessman had been on a long flight between meetings. After a while, a calm voice said, “We shall not be serving the drinks at this time as we are expecting a little turbulence(漩涡). Please be    1    your seat belt is fastened.”

Lightning    4    the darkening skies, and within moments that great plane was like a _  5    moving around on an ocean. One moment the airplane was    6    on terrific currents of air; the next, it dropped as if it were about to crash. All the passengers were upset and scared. Some were praying. The future seemed terrible and many were wondering if they would    7    it through the storm.
