构造了绕极电流的Sverdrup型解。它解释了洋流的南移，但要求洋流完全位于最大西风带以南。然而，观测表明，风和海流几乎重合，风带和海流都显示出向南移动。使用摩擦模型，克服了这一差异，并允许完全详细地计算电流的横向环流。对不同风况下的横向环流进行了计算和讨论，结果表明各种辐散和辐合的分布和强度对风有很强的依赖性。对南极极锋给出了新的解释。根据风况的不同，认为这是一种辐合或发散现象。
A Sverdrup-type solution of the Circumpolar Current is constructed. It explains the southward shift of the current, but requires that the current is situated completely to the south of the maximal westerlies. The observations show, however, that winds and current almost coincide and that both, the wind belt and the current, show a shift to the south. A frictional model is used, which overcomes this discrepancy and allows the calculation of the transverse circulation of the current in full detail. The transverse circulation under different wind conditions is calculated and discussed and shows a strong dependence of the distribution and intensity of the various divergences and convergences on the wind. A new interpretation of the Antarctic Polar Front is given. It is regarded as a convergent or divergent phenomenon according to the wind conditions.
