本文利用一个高分辨率的海洋模式（1/8 × 1/12，85层），结合实际的几何条件和强迫条件，计算了南大洋等密度层厚度的扩散系数。据发现，该系数是大的阿根廷盆地，Agulhas Retroflection区，和东部的Kerguelen褶皱在2000米的深度。大系数区域与斜压不稳定的高增长率区域相吻合。
Using a high-resolution ocean model (1/8 × 1/12, 85 levels) with realistic geometry and forcing, the diffusion coefficient of the isopycnal thickness is evaluated in the Southern Ocean. It is found that the coefficient is large in the Argentine Basin, the Agulhas Retroflection region, and the east of the Kerguelen Pleatue at 2000 m depth. The large coefficient regions coincide with high growth rate regions of the baroclinic instability.
