The following sub-grid scale parameterizations generally yield fluxes that act in the vertical direction, with no lateral components resolved by the model.
- K-profile parameterization (KPP)
Provided by module MOM_KPP, uses the CVmix implementation of KPP.
:ref:`CVMix_KPP`
- Energetic Planetary Boundary Layer (ePBL)
A energetically constrained boundary layer scheme following :cite:`reichl2018`. Implemented in MOM_energetic_PBL.
:ref:`EPBL`
- Bulk mixed layer (BML)
A 2-layer bulk mixed layer used in pure-isopycnal model. Implemented in MOM_bulk_mixed_layer.
:ref:`BML`
- Kappa-shear
- MOM_kappa_shear implements the shear-driven mixing of :cite:`jackson2008`.
Internal-tide driven mixing
The schemes of :cite:`st_laurent2002`, :cite:`polzin2009`, and :cite:`melet2012`, are all implemented through MOM_set_diffusivity and MOM_diabatic_driver.
:ref:`Internal_Vert_Mixing`
Vertical viscosity is implemented in MOM_vert_frict and coefficient computed in MOM_set_viscosity, although contributions to viscosity from other parameterizations are calculated in those respective modules (e.g. MOM_kappa_shear, MOM_KPP, MOM_energetic_PBL).
:ref:`Vertical_Viscosity`
Vertical diffusion of scalars is implemented in MOM_diabatic_driver although contributions to diffusion from other parameterizations are calculated in those respective modules (e.g. MOM_kappa_shear, MOM_KPP, MOM_energetic_PBL).
- Opacity
- Ocean color is prescribed or dynamically calculated in converted into optical properties in MOM_opacity.
- Short-wave absorption
- Optical properties from MOM_opacity are used to calculate the convergence of shortwave radiation penetrating from the upper surface in MOM_shortwave_abs.
Geothermal heat fluxes are implemented in MOM_geothermal.
Diapycnal diffusion in a layered isopycnal mode following :cite:`hallberg2000`, is implemented in MOM_entrain_diffuse.
