斜压大气中涡旋运动方程及其在天气预报中的应用

本文根据流体力学的基本理论,得出了斜压大气中的涡旋运动方程。并讨论了决定涡旋运动的六个基本因子。对日常应用的高空引导观念给予比较明确的物理解释并加以修正。文中对这方程在预报台风移动的应用作了初步说明,也附带简单地谈到了中纬度系统的移动。在附录中还指出了关于系统内力作用的误解,并简单地讨论了台风运动的摆动周期和振幅。

THE EQUATIONS OF MOTION OF VORTICES IN BAROCLINIC ATMOSPHERE AND THEIR APPLICATION IN WEATHER FORECASTING

In this paper,the equations of motion of vortices in baroclinic atmosphere are derived in the light of classical hydzodynanucs.Six factors determining the motion of vortices are discussed.Physical interpretation and some coazments are given to the well-known steering principle.Application of these equations in the forecasting of the motion of typhoons are illustrated by three examples,and the results are better or as well as those of the synoptic forecasts.Possibility and limitation of their application to the motion of middle-latitude vortices are also discussed.In the appendix,there are critical discussions of the role of the internal forces and the calculation of the amplitude and period of the meandering motion of typhoons in straight steering current.
