Small increases in temperature found to add power to storms in the Atlantic.
研究發(fā)現(xiàn)，氣溫的小幅上升會增加大西洋風暴的威力。

Hurricanes that form in the Atlantic Ocean are expected to gain considerable strength asthe global temperature continues to rise, a new study has found.
一項新的研究發(fā)現(xiàn)，隨著全球氣溫的持續(xù)上升，在大西洋形成的颶風預計將獲得相當大的威力。

Using modeling data focused on the conditions in which hurricanes form, a group ofinternational researchers based at Beijing Normal University found that for every 1.8°F ( 1℃ )rise of the Earth's temperature, the number of hurricanes in the Atlantic that are as strong orstronger than Hurricane Katrina will increase twofold to sevenfold.
北京師范大學的一組國際研究人員利用以颶風形成條件為重點的建模數(shù)據(jù)發(fā)現(xiàn)，地球溫度每上升 1.8 華氏度（1℃），大西洋中強度與卡特里娜颶風相當或更強的颶風數(shù)量將增加兩倍到七倍。

Hurricane strength is directly related to the heat of the water where the storm forms. Morewater vapor in the air from evaporating ocean water adds fuel to hurricanes that build strengthand head toward land.
颶風的強度與風暴形成地的海水熱量直接相關。海水蒸發(fā)后空氣中的水蒸氣增多，為颶風增添了燃料，使颶風強度增強，并向陸地移動。

Hurricane Katrina is widely considered the measure for a destructive storm, holding themaximum Category 5 designation for a full 24 hours in late August 2005. It lost strength as itpassed over the Florida peninsula, but gained destructive power fight before colliding withNew Orleans, killing more than 200 people and causing $ 80 billion in damage.
卡特里娜颶風被廣泛認為是衡量破壞性風暴的標準，它在 2005 年 8 月下旬的整整 24 小時內(nèi)都保持著 5 級的最高強度。它在掠過佛羅里達半島時減弱了力量，但在與新奧爾良相撞前又增強了破壞力，造成 200 多人死亡，800 億美元的損失。

The study points to a gradual increase of Katrina-like events. The warming experiencedover the 20th century doubled the number of such debilitating(將人類摧垮的)storms. But theongoing warming of the planet into the 21st century could increase the frequency of theworst kinds of storms by 700 percent, threatening coastlines along the Atlantic Ocean withmuitiple Category 5 storms every year.
研究指出，類似卡特里娜的事件正在逐漸增多。20 世紀經(jīng)歷的氣候變暖使這種將人類摧垮的風暴的數(shù)量增加了一倍。但進入21世紀后，地球持續(xù)變暖可能會使最惡劣類型的風暴發(fā)生頻率增加700%，每年大西洋沿岸都會遭受數(shù)次5級風暴的威脅。

"Our results support the idea that changes in regional sea surface temperatures is theprimary cause of hurricane variability," said Aslak Girnstead, a researcher with the Center forIce and Climate at the University of Copenhagen. The large impact of small sea-surfacetemperature increases was more than Girustead and his colleagues had anticipated. Theentire study was published in the Proceedings of the National Academy of Sciences.
“哥本哈根大學冰與氣候中心研究員阿斯拉克-吉恩斯泰德說：”我們的研究結(jié)果支持了這樣一種觀點，即區(qū)域海面溫度的變化是颶風多變性的主要原因。哥本哈根大學冰與氣候中心的研究員阿斯拉克-吉恩斯泰德說："海面溫度的小幅上升所產(chǎn)生的巨大影響超出了吉恩斯泰德和他的同事們的預料。整個研究發(fā)表在《美國國家科學院院刊》上。

Global temperatures have steadily increased, making the past decade the warmest onrecord. Earlier this year, climate researchers reported that the Earth's temperatures have risenfaster in the last century than at any point since the last ice age, 11,300 years ago. Theprimary cause, a couseusus of scientists has said, is the rising emissions of greenhousegases like carbon dioxide and methane.
全球氣溫穩(wěn)步上升，使過去十年成為有記錄以來最熱的十年。今年早些時候，氣候研究人員報告說，上個世紀地球氣溫的上升速度超過了11300年前上一個冰河時期以來的任何時期。科學家們表示，主要原因是二氧化碳和甲烷等溫室氣體的排放量不斷增加。

Past hurricanes have supported the study's finding that global temperature rise is linkedto more destructive storms. According to the National Center for Atmospheric Research, whilethe frequency of storms doesn't appear to have increased, the percentage of strong ones hasrisen sharply over the past few decades. The trend may be similar further back in time, butcomprehensive hurricane data doesn't exist.
過去的颶風支持了這項研究的結(jié)論，即全球氣溫上升與更具破壞性的風暴有關。根據(jù)美國國家大氣研究中心的數(shù)據(jù)，雖然風暴的頻率似乎并沒有增加，但是強風暴的比例在過去幾十年中急劇上升。這種趨勢在更久遠的年代可能也是類似的，但目前還沒有全面的颶風數(shù)據(jù)。

【答案解析】

1.答案：C
解析：本題關注地球溫度上升對颶風頻率和強度的影響。定位句明確指出，當?shù)厍驕囟让可仙?.8華氏度（即1攝氏度）時，大西洋中強度與卡特里娜颶風相當或更強的颶風數(shù)量會顯著增加，從兩倍到七倍不等。因此，C選項“更多像卡特里娜那樣或是更糟糕的颶風”準確反映了這一變化。

2.答案：D
解析：本題探討颶風形成區(qū)域中海水的作用。根據(jù)定位句，從海洋中蒸發(fā)到空氣中的水分越多，颶風的威力就越強，隨后這些颶風會直接襲擊陸地。這說明了海水蒸發(fā)成水蒸氣是增強風暴威力的關鍵過程。因此，D選項“蒸發(fā)成水蒸氣，使得風暴威力增強”準確概括了這一現(xiàn)象。

3.答案：B
解析：本題要求理解卡特里娜颶風的具體影響。定位句指出，卡特里娜颶風在到達新奧爾良州之前強度顯著增加，其巨大的破壞力導致了超過200人的死亡，并造成了高達800億美元的經(jīng)濟損失。因此，B選項“卡特里娜颶風造成了大量的人員傷亡和經(jīng)濟損失”是對這一事件影響的準確描述。

4.答案：A
解析：本題分析局域海面溫度變化對颶風的影響。定位句強調(diào)，局域海面溫度的變化是颶風變化的主要原因。這意味著海面溫度的變化直接影響颶風的形成、發(fā)展和強度。因此，A選項“局域海面溫度的變化對颶風造成顯著影響”準確地概括了這一關系。

5.答案：B
解析：本題探討減少溫室氣體排放對緩解破壞性風暴頻率的作用。根據(jù)倒數(shù)第二段和最后一段的信息，全球變暖是由溫室氣體的大量排放引起的，而全球變暖與破壞性風暴頻率的增加之間存在關聯(lián)。由此可以推斷，減少溫室氣體的排放有助于減緩全球變暖的趨勢，進而可能降低破壞性風暴的發(fā)生頻率。因此，B選項“減少溫室氣體排放可能有助于減少破壞性風暴的發(fā)生”是合理的推斷。
