Description
Summary:Paper presented at the 33rd Annual conference of South African Society for Atmospheric Sciences (SASAS), 21-22 September 2017, Polokwane, South Africa. A one-dimensional ocean physical model was implemented in the sub-Antarctic Southern Ocean using the Nucleus for the European Modelling of the Ocean (NEMO) model. It was used to examine the effects of the turbulence response of the simulation of vertical mixing in the water column structure in the Southern Ocean (SO), using the available scattered data as comparison. The Brunt Väisälä frequency, turbulent diffusivity and turbocline provided valuable information regarding the turbulence response of the water column and the effect of an entrapped warm water parcel below cool waters was observed.
