Query: Implementation of a geometrically and energetically constrained
  mesoscale eddy parameterization in an ocean circulation model   The global stratification and circulation of the ocean and their
sensitivities to changes in forcing depend crucially on the representation of
the mesoscale eddy field. Here, a geometrically informed and energetically
constrained parameterization framework for mesoscale eddies --- termed
GEOMETRIC --- is proposed and implemented in three-dimensional primitive
equation channel and sector models. The GEOMETRIC framework closes mesoscale
eddy fluxes according to the standard Gent--McWilliams scheme, but with the
eddy transfer coefficient constrained by the depth-integrated eddy energy
field, provided through a prognostic eddy energy budget evolving with the mean
state. It is found that coarse resolution calculations employing GEOMETRIC
broadly reproduce model sensitivities of the eddy permitting reference
calculations in the emergent circumpolar transport, meridional overturning
circulation profile and the depth-integrated eddy energy signature; in
particular, eddy saturation emerges in the sector configuration. Some
differences arise, attributed here to the simple prognostic eddy energy budget
employed, to be improved upon in future investigations. The GEOMETRIC framework
thus proposes a shift in paradigm, from a focus on how to close for eddy
fluxes, to focusing on the representation of eddy energetics.
