Abstract:

Ocean models that incorporate the current parameterizations of Langmuir Turbulence reduce the shallow bias of the modelled boundary layer during austral summer in the Southern Ocean. We analyse an extensive dataset of microstructure observations of dissipation during austral summer in different regions of the Southern Ocean together with Large Eddy Simulations to build insight into how wind-wave driven Langmuir Circulations and Langmuir Turbulence impact the bulk statistics of observed TKE dissipation.
