英语翻译
In the second half of each year,many powerful storms are born in the tropical Atlantic and Caribbean seas .Of these.only about half a dozen generate the strong,circling winds of 75 miles per hour or more that give them hurricane status,and several usually make their way to the coast.There they cause millions of dollars of damage,and bring death to large numbers of people.
The great storms that hit the coast start as innocent circling distubances hundreds-even thousands-of miles out to sea.As they travel aimlessly over water warmed by the summer sun,they are carried westward by the trade winds.When conditions are just right,warm,moist air flows in at the bottom of such a disturbance,moves upward through it and comes out at the top.In the process,the moisture in this warm air produces rain,and with it the heat that is converted to energy in the form of strong winds.As the heat increases,the young hurricane begins to swirl in a counter-clock-wise motion.
The average life of ahurricane is only about nine days,but it contains almost more power than we can imagine.The energy in the heat released by a hurricane's rainfall in a single day would satisfy the entire electrical needs of the Untied States for more than six months.Water,not wind,is the main source of death and destruction in a hurricane.A typical hurricane brings 6-to-12-inch downpours resulting in sudden floods.Worst of all is the powerful movement of the sea-the mountains of water moving toward the low-pressure hurricane center.the water level rises as 15 feel above mormal as yt moves toward shore.
每年的下半年,热带大西洋和加勒比海上都会产生很多很有威力的风暴,其中只有约一半会形成至少每小时75英里的强烈带旋风,这些给了它们成了飓风的重要条件,有些会登陆海岸,造成数以百万计美金损失的破坏和大量人口的死亡.
侵袭海岸的大风暴最先在海上几百甚至几千英里外做无害的盘旋干扰.它们漫无目的的在被夏日阳光照暖的水上游移,被信风向西带去.当条件成熟,温暖潮湿的空气流入这股风暴的底部,在风暴内向上运动,又从顶部流出,在这个过程中,这股温暖空气中的湿气产生了雨,同时热量以强风的形式转换成能量.当热度上升,刚产生的飓风就开始逆时针方向盘旋.
一般一场飓风的持续时间是9天,但是它所携带的能量是我们无法想象的.飓风的降雨所释放的能量在一天里就可以满足整个美国6个多月的电力需要.水是飓风造成死亡和破坏的主要因素,而不是风.一场典型的飓风可带来6到12英寸豪雨,导致了突如其来的洪水.最坏的是海水的强大运动,如山高的水进入飓风中心的低压带.水位以高出正常15尺的高度向海滨移动.
最后一句我觉得很多地方拼错,按我的翻译,英文应该是the water level rises as 15 feet above normal as it moves toward shore.
我尽力了,嘿嘿~
