The name underscores their origin in the tropics and their cyclonic nature, which is that its circulation is counterclockwise in the northern hemisphere and clockwise in the southern hemisphere.

台风英语解说

形成：A typhoon is a mature tropical cyclone（热带气旋） that develops in the western part of the Pacific Ocean between 180° and100°E. Like any tropical cyclone, there are six main requirements for typhoon formation and development: sufficiently warm sea surface temperatures, atmospheric instability, high humidity in the lower to middle levels of the troposphere, enough Coriolis force to develop a low pressure center, a pre-existing low level focus or disturbance, and low vertical wind shear.台风在中国：china is one of the minority countries which have been effected seriously by typhoon. Some of the deadliest typhoons in history have struck China. Southern China has the longest record of typhoon impacts for the region, Taiwan has received the known typhoon on record for the northwest Pacific tropical cyclone basin.台风的影响：坏处The main effects of typhoon include heavy rain, strong wind, large storm surges at landfall, and tornadoes.

After the typhoon has passed, devastation often continues. It causes the spread of disease, and transportation or communications infrastructure may have been destroyed。

Influence of Typhoon
• Typhoon not only harms human beings,
• but also protects human beings. Typhoon has brought fresh water resources to human beings, greatly alleviating the global water shortage. A typhoon with a small diameter can bring 3 billion tons of precipitation when it lands. In addition, the typhoon also makes the cold and hot around the world keep relatively balanced.

平均风力达12级以上
台风给广大的地区带来了充足的雨水，成为与人类生活和生产关系密切的降雨系统。但是，台风也总是带来各种破坏，它具有突发性强、破坏力大的特点，是世界上最严重的自然灾害之一。
有条件时在船舶上配备信标机、无线电通讯机、卫星电话等现代设备。
在没有无线电通讯设备的时候，当发现过往船舶或飞机，或与陆地较近时，可以利用物件及时发出易被察觉的求救信号，如堆“SOS”字样，放烟火，发出光信号、声信号，摇动色彩鲜艳的物品等。
