【摘要】 本文给出了台风内力的新定义及其表达式。指出台风的内力是由台风区域内空气相对于台风移动的相对速度和上升运动产生的,其大小和方向决定于这种相对速度和相对加速度的非对称结构、台风的发展情况、上升运动速度和柯氏力随纬度的变化。文中还求得台风在内力作用下移动路径的表达式。从而可以看出台风在内力作用下极为复杂的曲线运动,这种运动是在惯性振荡的基础上叠加上由内力作用引起的波动。当内力为常数的情况下,台风在内力作用下的移动为振幅不同而周期相同的正弦波和余弦波叠加而成的摆动。更多还原

【Abstract】 In this paper, a new definition and expression of the internal force of typhoon are given. It is shown that the internal force is produced by the vertical motion and horizontal Telocity relative to the movement of typhoon of the ambient air. The Internal force depends on the asymmetric structure of the relative velocity and acceleration, development of typhoon, variation of Coriolis parameter with latitudes and vertical motion.Besides, the equations for the typhoon track under the effect of internal force have been derived. The equations show that the track of typhoon is very complicated. It is a wave that is a inertial oscillation superposed by waves produced by the internal force. When the internal force is constant, the track of typhoon is a curve constructed by a sine wave and a cosine wave with the same period but different amplitudes.更多还原
