tropical cycloneSevere atmospheric disturbance in tropical oceans.Tropical cyclones have very low atmospheric pressures in the calm, clear centre (the eye) of a circular structure of rain, cloud, and very high winds. In the Atlantic and Caribbean they are called hurricanes; in the Pacific they are known as typhoons. Because of the Earth's rotation, tropical cyclones rotate clockwise in the Southern Hemisphere and counterclockwise in the Northern. They may be 50–500 mi (80–800 km) in diameter, and sustained winds in excess of 100 mph (160 kph) are common. In the eye, however, the winds drop abruptly to light breezes or even complete calm. The lowest sea-level pressures on Earth occur in or near the eye. 热带气旋 tropical cyclone在热带海洋上形成的剧烈大气扰动。热带气旋中心(眼)的低气压带是晴朗平静的好天气，外部则环绕着降雨、云和强风。在大西洋和加勒比海的热带气旋被称作飓风，而在太平洋则被称作台风。由于地球的自转，热带气旋在南半球按顺时针方向运动，而在北半球则按逆时针方向运动。它们的直径可达到80～800千米，一般风速可保持在每小时160千米。但热带气旋的中心则只有微风甚至是平静的海面。地球上最低的海洋气压出现在热带气旋的中心或中心附近。气旋出现在热带纬度，由温暖的空气和水驱动。风环绕低压中心“风眼”转动，中心通常无风。在风眼壁里面或附近风雨通常最为猛烈。A severe tropical cyclone originating in the equatorial regions of the Atlantic Ocean or Caribbean Sea, traveling north, northwest, or northeast from its point of origin, and usually involving heavy rains.飓风：一种猛烈的热带风暴，形成于大西洋或加勒比海赤道地区，从形成地向北、西北或东北移动，通常携有大量雨水A wind with a speed greater than 74 miles (119 kilometers) per hour, according to the Beaufort scale.暴风：按照蒲氏风级，时速达74英里(119公里）以上的风

我国是一个自然灾害频繁而又严重的国家，每年都有一些地区遭受干旱、洪涝、滑坡、泥石流、台风、冰雹、霜冻、病虫鼠草等灾害的袭击，地震灾害也时有发生，给人民生命财产造成严重损失。China is a frequent natural disasters and the country every year, in some areas drought, 洪涝, landslides, the frost, typhoons, the hail, the grass, waiting for disasters and pests and diseases should attack. the earthquake, disaster can also occur to the people's lives and property incurred severe losses.1.earthquake calamity地震灾害中国除贵州、浙江省外，各省均发生过6级以上地震，其中发生过7级以上强震的省、自治区、直辖市就有19个。全国7级以上高烈度区的面积达312万平方公里，占国土面积的32％。全国45％的大中城市位于烈度为7度或7度以上的高烈度区。China except outside Guizhou, Zhejiang Province, various provinces has 6 magnitude of above earthquakes, in which has had 7 level of above macroseism provinces,the autonomous region, the municipality has had 19.The national 7 level of above high intensity area area amounts to 3,120,000 square kilometers, occupies thenational territory area 32%.The national 45% big or media-sized cities are located the intensity are 7 degree or 7 degree above high intensity areas.2.aridity calamity干旱灾害水资源持续减少。The water resources reduce continually.湖泊水位降低，水面缩小甚至干涸。The lake water level reduces, the water surface reduces even dry.冰川退缩和变薄 The glacier flinches and changes thin沙漠化土地明显扩展。Desertification land obvious expansion.3.spate calamity洪涝灾害多年来，由于盲目开垦砍伐，使植被大面积丧失，造成水土流失、江河泥沙淤积，河床抬高。For many years, because blindly has opened up wasteland the felling, causes the vegetation big area to lose, creates the soil erosion, the rivers and streams silt siltation, the river bed run-up.4.soil erosion 水土流失我国是世界上水土流失最严重的国家之一，每年流失土壤50多亿吨，占世界总流失量（600亿吨〕的1／12，每年的入海泥沙量约20亿吨，亦占世界陆地人海泥沙量（240亿吨）的1／12。Our country is in the world one of soil erosion most serious countries, drains the soil more than 50 hundred million tons every year, occupies the world always drains the quantity (60,000,000,000tons) 1/12, every year enters the sea silt quantity approximately 2,000,000,000 tons, also accounts for the world land huge crowd silt quantity (24,000,000,000 tons) 1/12.5.landslide 滑坡如人为的爆破作用、开挖坡脚或矿坑、坡面上堆填加载、生产和生活用水下渗等改变了原有的地质环境，破坏了平衡，矿山、铁路、水库旁的山体滑坡主要是这个原因。If the artificial demolition effect, excavated on the toe of slope or the mine pit, the slope face the pile fills in under the load, the production and the domestic water infiltrates and so on to change the original geological environment, destroyed the balance, nearby the mine, the railroad, the reservoir mountain massif landslide mainly is this reason.人类的不合理生产活动，导致了环境的恶化，环境的恶化诱发或加重了自然灾害的发生，而自然灾害的发生又进一步破坏了环境，对人类进行了无情的报复，这是一个恶性循环。为了防止或减缓这一恶性循环的发生和延续，就必须充分发挥人类社会的调控机能，遵循自然规律，在人与自然环境之间寻求和谐的关系，改善环境，减轻灾害，为人类生存和社会发展创造更加美好的环境条件。The humanity produces the activity not reasonably, has caused the environment worsening, the environment worsened suggestion or aggravated the natural disaster occurrence, but the natural disaster occurrence further destroyed the environment, has carried on the heartless retaliation to the humanity, this is a vicious circle.In order to prevent or slows down this vicious circle the occurrence and the extension, must display the human society fully the regulative function, the deference natural law, seeks the harmonious relations between the human and the natural environment, the improvement environment, reduces the disaster,creates the happier environmental condition for the human survival and the social development.

A Pacific typhoon or tropical storm is a tropical cyclone that forms in the northwestern Pacific Ocean. The basin is demarcated within the Pacific Ocean from Asia, north of the equator, and west of the international date line.Storms from the Eastern and Central Pacific crossing the date line are re-designated as typhoons. This basin features the strongest cyclones on record.Typhoon seasons include the entirety of the calendar year. Most storms tend to form between May and November, although they can occur at other times of the year as well.
