From Arctic high, Antarctic low to three-dimensional hetero clinic orbit connecting south p ole and north p ole

摘要: 本文利用球坐标系(λ，φ， r)中的球面地转风关系，说明当等压线形成最简单的纬向分布时，此时南极是低压，北极是高压。但是，当在地转风关系中加入摩擦力后，则南北极由闭合涡旋变成螺旋涡旋，且两极之间形成一条球面上的三维异宿轨道。

Abstract: Under the steady condition, the spherical geostrophic wind relationship in spherical coordinates (λ,φ, r) is applied to illustrate that when isobars take the simplest zonal distribution, the Antarctic is at a low ambient pressure, while the Arctic is at high. However, when friction is incorporated into the geostrophic wind relationship, the closed vortex over Antarctic and Arctic will turn to a spiral vortex, and there will exist a three-dimensional heteroclinic orbit between Antarctic and Arctic on the spherical surface.
