Lower Isopycnal Diffusivity in the ocean
This was suggseted during a conversation with Jonathan and Willem Sijp as being likely to reduce the warm bias found throughout the Southern Ocean. A reduction of 25% didn’t do much, but reducing it to 50% seemed to cool the SO at the surface and below the depth of the NADW intrusion - which did get slightly stronger, causing some warming at mid-depth.

Till Kuhlbrodt@Reading is, additionally, looking at how the GM parameters affect the ACC, along with assessing how the inclusion of the spatial-dependent Visbeck parameterisation of the GM coefficients affect FAMOUS.
