台风的成因 太阳直射的持续高温的太平洋的夏日,大面积的洋面上的水分大量蒸发。不断蒸发的水分将逐渐排斥空气中的其它气体成分,使空气的湿度急剧增加。这种高湿度的空气,正是台风的形成的先决条件! 当有外部条件(如降温或水蒸气自动凝结)促使高湿度的空气的水分凝聚时,空气的压强会急剧下降,造成了相对于周围空间的大气负压,而这种负压就是形成台风的中心负压。这种负压一旦形成,周围的空气就会立刻进行补充。由于负压往往是从低温度的高空开始形成的,因而也就形成了自下而上且周围向中心旋转的空气大旋涡——这就是台风眼! 因而,台风的成因来自于空气的负压,负压来自于水蒸气的凝结,水蒸气来自于太阳的夏日的连续直射所产生的高温!最终,太阳是导致台风产生的根本动因! 对上述的假说的最主要的证据,就是台风都是在海面上形成的,且是在太阳直射、持续炎热的夏日,并且,当台风逐步经海面登陆陆地的时候,会逐渐减弱为低气压而逐渐消失,这是因为台风经过的海面都是高湿度的空气的水分逐次凝结的区域,而陆地上空的空气的湿度则相对要低的多,因而不能形成强的空气负压中心,也就只能成为陆地风暴而不能成为台风了。 了解台风形成的真正成因与机理,不但能够使我们能够了解自然,还会使我们更能容易的把握自然!
