Summary
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.
