| 摘 要： | 将Eliassen建立在平面等压柱坐标系中的径向环流强迫理论（用于研究在摩擦力和非绝热加热过程影响下的静止对称涡旋），推广应用到研究移动非对称气旋或反气旋的径向环流，导出了考虑地球曲面影响的准拉格朗日等压柱坐标系的切向平均径向环流诊断方程，并根据Eliassen的解析解所揭示的涡旋径向环流在涡旋演变中的作用，定 性地讨论了各种热力和动力的作用，这些热力和动力因子除了磨擦力和非绝热加热外，还有平均和涡动形式的惯性力，角动量平流（相当涡度平流），角动量的垂直对流，温度平流，温度的垂直对流（相当绝热加热）等。

| Abstract: | A linear partial differential equation is derived in cylindrical-isobaric coordinates on the earth for the diagnostic study of the tangentially-averaged radial-vertical circulation within translating vortices. In the hydrodynamic stable atmosphere, the circulation will be forced through many dynamic and thermodynamic processes. These processes are associated with frictional torque, inertial torque, the horizontal and vertical divergence of eddy angular momentum, diabatic heating, adiabatic heating, and eddy temperature advection. For a given forcing, the intensity of circulation will increase with the decrease of static, inertial,and baroclinic stabilities. This paper also presents an explanation on the data interpolation from the latitude-longitude grid to the vortex volume gird and a brief discussion on the forcing processes. |
