Hurricanes are violent storms that cause millions of dollars in property damage and take many lives. They can be extremely dangerous, and too often people underestimate their fury. Hurricanes normally originate as a small area of thunderstorms over the Atlantic Ocean west of the Cape Verde Islands during August or September. For several days, the area of the storm increases and the air pressure falls slowly. A center of low pressure forms, and winds begin to whirl around it. It is blown westward, increasing in size and strength. Hurricane hunters then fly out to the storm in order to determine its size and intensity and to track its direction. They drop instruments for recording temperature, air pressure, and humidity (湿度), into the storm. They also look at the size of waves on the ocean, the clouds, and the eye of the storm. The eye is a region of relative calm and clear skies in the center of the hurricane. People often lose their lives by leaving shelter when the eye has arrived, only to be caught in tremendous winds again when the eye has passed. once the forecasters have determined that it is likely the hurricane will reach shore, they issue a hurricane watch for a large, general area that may be in the path of the storm. Later, when the probable point of landfall is clearer, they will issue a hurricane warning for a somewhat more limited area. People in these areas are wise to stock up on nonperishable foods, flash light and radio batteries, candles, and other items they may need if electricity and water are not available after the stoma. They should also try to hurricane-proof their houses by bringing in light-weight furniture and other items from outside and covering windows. People living in low-lying areas are wise to evacuate their houses because of the storm surge, which is a large rush of water that may come ashore with the storm. Hurricanes generally lose power slowly while traveling over land, but many move out to sea, gather up force again, and return to land. As they move toward the north, they generally lose their identity as hurricanes. The eye of the hurricane is ______ .

根据下面资料，回答下列各题。 Small increases in temperature found to add power to storms in

the Atlantic. Hurricanes that form. in the Atlantic Ocean are expected to gain considerable strength as the global temperature continues to rise, a new study has found. Using modeling data focused on the conditions in which hurricanes form, a group of international researchers based at Beijing Normal University found that for every 1.8°F (1℃ )rise of the Earths temperature, the number of hurricanes in the Atlantic that are as strong or stronger than Hurricane Katrina will increase twofold to sevenfold. Hurricane strength is directly related to the heat of the water where the storm forms. More water vapor in the air from evaporating ocean water adds fuel to hurricanes that build strength and head toward land. Hurricane Katrina is widely considered the measure for a destructive storm, holding the maximum Category 5 designation for a full 24 hours in late August 2005. It lost strength as it passed over the Florida peninsula, but gained destructive power fight before colliding with New Orleans, killing more than 200 people and causing $ 80 billion in damage. The study points to a gradual increase of Katrina-like events. The warming experienced over the 20th century doubled the number of such debilitating(将人类摧垮的)storms. But the ongoing warming of the planet into the 21st century could increase the frequency of the worst kinds of storms by 700 percent, threatening coastlines along the Atlantic Ocean with muitiple Category 5 storms every year. "Our results support the idea that changes in regional sea surface temperatures is the primary cause of hurricane variability," said Aslak Girnstead, a researcher with the Center for Ice and Climate at the University of Copenhagen. The large impact of small sea-surface temperature increases was more than Girustead and his colleagues had anticipated. The entire study was published in the Proceedings of the National Academy of Sciences. Global temperatures have steadily increased, making the past decade the warmest on record. Earlier this year, climate researchers reported that the Earths temperatures have risen faster in the last century than at any point since the last ice age, 11,300 years ago. The primary cause, a couseusus of scientists has said, is the rising emissions of greenhouse gases like carbon dioxide and methane. Past hurricanes have supported the studys finding that global temperature rise is linked to more destructive storms. According to the National Center for Atmospheric Research, while the frequency of storms doesnt appear to have increased, the percentage of strong ones has risen sharply over the past few decades. The trend may be similar further back in time, but comprehensive hurricane data doesnt exist. According to the team of international researchers based at Beijing Normal University, the rise of the Earths temperature is likely to cause

A.the coming of ice age

B.more Katrina-like or worse hurricanes

C.less intense hurricanes

D.more greenhouse gases in the atmosphere
