本文研究了正方形海盆内两层海洋的风驱动环流，以描述观测到的西边界流分离。允许下层浮出水面，上层深度沿其消失的线沿着解释为表面温跃层的区域。对于有代表性的风应力，该理论预测了墨西哥湾流的总体特征，该区域邻近包含分离边界流的浮出水面线。通过假设摩擦和惯性的影响仅限于边界层特征的区域，分离流的位置仅取决于分层的程度和所施加的风应力的某些积分性质。
A study is made of the wind-driven circulation of a two-layer ocean within a square basin, with a view to describing the observed separation of western boundary currents. The lower layer is allowed to surface and the line along which the upper-layer depth vanishes is interpreted as the region of the surfacing thermocline. For a representative wind stress the theory predicts the gross features of the Gulf Stream flow, the region adjacent to the surfacing line containing the separated boundary current. By assuming that the effects of friction and inertia are confined to regions of a boundary-layer character, the position of a separated current is shown to depend only on the degree of stratification and certain integral properties of the applied wind stress.
