| 摘 要： | 热带气旋在移动过程中，环境气压场和其自身内力等都在发生变化。假设这些影响热带气旋的力之和随时间的变化在某一时段内是张性的，从而导出热带气旋的路径曲线方程。分析方程，得逞以热带气旋移动的三个基本规律。通过实例计算，可以看到方程曲线与实际路径几乎一致的个例验证结果，并有意义地证实一些人们以前的研究成果。

| Abstract: | The tropical cyclone motion is affected by many factors, such as the internal structure,the atmospheric temperature and the land conditions.However, the pressure gradient force of the environmental field and the internal force of the tropical cyclone are most important.The general solution of governing equation of the tropical cyclone motion is derived assuming the variation of these forces is linear with the time.Also the three basic rules of the tropical cyclone motion are derived from the general solution of governing equation.Some achievements in scientific research of tropical cyclones can be verified through the calculation and analysis the general solution. |
