　　Typhoon formation The typhoon origin,until now still was unable extremely todetermine,but known it is comes by the tropics atmosphere inperturbation development.On the tropics sea,the sea level because ofcauses the vertical incident solar rays the sea temperature toelevate,the sea water is easy to evaporate the water vapor to spreadin airborne,therefore on tropics sea air temperature high,humiditybig,this kind of air high inflates because of the temperature,causesthe density to reduce,the quality reduces,but nearby equator windpower weak,therefore is very easy to rise,has the convectioncurrent,simultaneously periphery the colder air inflow supplemented,then rises again,so moves in endless cycles,the end must entirecause for the temperature higher,the weight to be all lighter,a density smaller air,this has formed so-called "the tropicaldepression".However flowing of the air is the proud barometricpressure flows to the low atmospheric pressure,looks like is thewater flows to the low spot from the high place to be same,all aroundthe barometric pressure compares the high place the air to have tocompare the low spot to the barometric pressure to flow,but forms"the wind".In summer,because the vertical incident solar rays regionmoves by the equator to the north,causes of southeast trade crossingthe line the southern hemisphere to change the southwest monsoon toinvade Northern Hemisphere,meets one another with the originalNorthern Hemisphere's Northeast Tradewind,compels crowds this airrise,the increase convection current,again because the southwestmonsoon and the Northeast Tradewind direction is different,meets oneanother often creates the undulation and the whirlpool.This kind ofsouthwest monsoon and the Northeast Tradewind meet one another thespoke which creates to gather the function,with the originalconvection current continuously,causes to form continues for the lowatmospheric pressure whirlpool to deepen,when is causes all aroundthe air speeds up to the whirlpool center class,the inflow quickly,its wind speed is bigger; When the near ground most gale fast arrivesor surpasses each second 17.2 meters,we called it is the typhoon.Saw from the typhoon structure,the so giant colossus,it producesmust meet the unique requirement.First,must have broad high temperature,the humidity atmosphere.Thetropics on first floor atmosphere temperature and the humiditymainly decided to the sea level water temperature,the typhoon onlycan form Yu Haiwen is higher than 26 ℃ - 27 ℃ is warm on,moreover in 60 meters depths sea water water temperatures all must behigher than 26 ℃ - 27 ℃; Second,must have the lower atmosphere high level to gather,theinitial perturbation to the central spoke which proliferates tooutside.Moreover the high level spoke disperses must surpass theunderlying bed spoke to gather,can maintain the enough ascendantcurrent,the underlying bed perturbation can unceasingly strengthen; Third,the vertical direction wind speed cannot differ too in a bigway,on the lower level air relative motion is very small,can causeto dive the heat energy centralism preservation which in the initialperturbation the water vapor congeals releases in the area center,forms and strengthens the typhoon warm centerstructure Fourth,must have the enough big place to transfer thefunction,the earth rotation function is advantageous to the cyclonevortex production.Transfers approaches nearby the equatorto zero,increases to the north and south two-pole,the typhoon occursprobably is leaving above the equator 5 latitudes on.

To weak buildings, all kinds of lines, trees overhead, ships at sea, and the sea, and the sea cages fish such as a destructive crops. 5 typhoon is often accompanied by heavy rain, the sea happened tide, big tsunami. Six is strong typhoon occurs, the force majeure, easy cause casualties.

　　中文：台风是热带气旋的一个类别。在气象学上，按世界气象组织定义：热带气旋中心持续风速达到12级。

　　台风根据近几年来台风发生的有关资料表明，台风发生的规律及其特点主要有以下几点：一是有季节性。台风(包括热带风暴)一般发生在夏秋之间，最早发生在五月初，最迟发生在十一月。二是台风中心登陆地点难准确预报。台风的风向时有变化，常出人预料，台风中心登陆地点往往与预报相左。三是台风具有旋转性。其登陆时的风向一般先北后南。四是损毁性严重。对不坚固的建筑物、架空的各种线路、树木、海上船只，海上网箱养鱼、海边农作物等破坏性很大。五是强台风发生常伴有大暴雨、大海潮、大海啸。六是强台风发生时，人力不可抗拒，易造成人员伤亡。
