台风的成因,至今仍无法十分确定,但已知它是由热带大气内的扰动发展而来的.在热带海洋上,海面因受太阳直射而使海水温度升高,海水容易蒸发成水汽散布在空中,故热带海洋上的空气温度高、湿度大,这种空气因温度高而膨胀,致使密度减小,质量减轻,而赤道附近风力微弱,所以很容易上升,发生对流作用,同时周围之较冷空气流入补充,然后再上升,如此循环不已,终必使整个气柱皆为温度较高、重量较轻、密度较小之空气,这就形成了所谓的「热带低压」.然而空气之流动是自高气压流向低气压,就好像是水从高处流向低处一样,四周气压较高处的空气必向气压较低处流动,而形成「风」.在夏季,因为太阳直射区域由赤道向北移,致使南半球之东南信风越过赤道转向成西南季风侵入北半球,和原来北半球的东北信风相遇,更迫挤此空气上升,增加对流作用,再因西南季风和东北信风方向不同,相遇时常造成波动和旋涡.这种西南季风和东北信风相遇所造成的辐合作用,和原来的对流作用继续不断,使已形成为低气压的旋涡继续加深,也就是使四周空气加快向旋涡中心流,流入愈快时,其风速就愈大;当近地面最大风速到达或超过每秒17.2公尺时,我们就称它为台风.

Typhoon causes are still not fully determined, but it is known from the tropical atmospheric disturbances from development. In tropical oceans, the sun shone directly on the surface because the water temperature so that water evaporation into aqueous easily spread in the air, on the tropical marine air temperature is high, high humidity, such as air temperature and high inflation, resulting in reduced density, reduced quality, and near equatorial wind weak, so it is easy to rise, the role of convection, At the same time the more air flow around complement, and then rising, so the cycle, the temperature will be the entire column ozone were higher, lighter, smaller density of air, which formed a so-called "tropical low voltage." But the flow of air pressure is mixed flow low pressure, low flow like water from a height Office, the Office of higher pressure surrounding air will flow to the pressure low Department, and a "wind". In summer, because the sun shone directly on the equatorial region to the north, leaving the southern hemisphere of the southeast winds across the equator to the southwest monsoon incursions into the northern hemisphere, and the northeast winds in the northern hemisphere come more to squeeze the air rise, increasing the role of convection, and then for the south-west monsoon and the northeast winds in different directions, each often caused fluctuations and vortex. This southwest monsoon and northeast winds caused by the conflict in cooperation spoke of a wheel, and the continuing role of convection, the formation of low pressure that has continued to deepen the vortex, that is to speed up the air around the center vortex flow, flow more rapidly, its wind speed on older; When the wind speed reaches or exceeds the largest ground 17.2 meters per second, we call typhoons.
