一个传统的海洋模式进行了修订，包括速度的趋势，放松对最大熵的解决方案，这取决于地形的形状。这种趋势，称为地形应力，产生极地东部边界暗流，加强赤道深西部边界电流，维持深阿拉斯加流，并有助于深水交换。虽然地形应力的影响是最清楚地看到在深度，表面表达式包括减少西部边界电流分离的过冲，从而限制了隐含的海气热量和淡水通量附近的这些分离。
A conventional ocean model was revised to include a tendency for velocities to relax toward a maximum entropy solution that depends on the shape of topography. The tendency, called topographic stress, generates poleward eastern boundary undercurrents, strengthens equatorward deep western boundary currents, sustains a deep Alaska Stream, and contributes to deep water exchange. Although the influence of topographic stress is most clearly seen at depth, surface expressions include reducing the overshoot of western boundary current separation, thereby limiting implied air-sea heat and freshwater fluxes near these separations.
