摘要
本文在广泛的意义下导出了热带气旋瞬时移向所满足的一阶拟线性偏微分方程,并得到了一般解的表达式。同时也导出了相应的移速计算公式。然后,利用对解案的分析指出了热带气旋移动存在着突变现象。从而说明了热带气旋移动过程中某些“古怪”行为的发生。
In this paper the first order quasi-linear partial differential equation for instantaneous moving direction of tropical cyclone has been derived in a general sense, and its general solution has been obtained. The formula for moving speed has also been derived. These expressions involve the equations which were used by G. Holland to calculate the direction and speed in tropical cyclone movement. From the analyses of the solution, it is indicated that catastrophic phenomena exist in tropical cyclone motion, thus explaining the appearance of some'ertatic behaviour' in the process of tropical cycloen motion. It is indicated that caution should be taken in using Holland's method.
