The turbulence model

To close the differential equations for momentum, heat, and salt, parameterisations of the turbulent fluxes of momentum, $ {\langle u' w' \rangle} $, heat $ {\langle w'\theta' \rangle} $, and salinity $ {\langle w's' \rangle} $ are required. Since turbulence `feels' the effects of temperature and salinity fluctuations essentially through buoyancy fluctuations, only the buoyancy flux, $ {\langle w'b' \rangle} $, is discussed in the following. The assumptions under which one can infer the fluxes of heat and salinity from the buoyancy flux are addressed below.
