TLDR
In this article, the first baroclinic deformation radius to the horizontal grid spacing indicates where an ocean model could explicitly simulate eddy effects; a function of this ratio can be used to specify where eddy effect are parameterized and where they are explicitly modeled.About:

Point-by-point reply to reviewer 1
TL;DR: In this paper, a multidecadal time scale in the occurrence of these Maud Rise polynyas was found, and it was shown that a preferred time scale can be induced by the variability of the Weddell Gyre, previously identified as the Southern Ocean Mode.

Sensitivity of simulated water mass transformation on the Antarctic shelf to tides, topography and model resolution
Fabio Boeira Dias,Stephen R. Rintoul,Ole Richter,Benjamin K. Galton-Fenzi,Jan D. Zika,Violaine Pellichero,Petteri Uotila +6 more
TL;DR: In this article , the authors used a circum-Antarctic ocean-ice shelf model to assess the contribution of surface fluxes, mixing, and oceanice shelf interaction to the water mass transformation (WMT) on the continental shelf.

On the ocean's response to enhanced Greenland runoff in model experiments: relevance of mesoscale dynamics and atmospheric coupling
Torge Martin,Arne Biastoch +1 more
TL;DR: In a suite of eight dedicated 60- to 100-year-long model experiments with and without atmospheric coupling, with eddy processes parameterized and explicitly simulated and with regular and significantly enlarged Greenland runoff, the authors find a major impact by the interactive atmosphere in enabling a compensating temperature feedback, and a non-negligible influence by the ocean mean state biased towards greater stability in coupled simulations, both of which make the Atlantic meridional overturning circulation less susceptible to the freshwater perturbation applied, and

Keep it simple: A low-complexity model to study scale dependence of phytoplankton dynamics in the tropical Pacific
Jozef Skákala,Paolo Lazzari +1 more
TL;DR: It is demonstrated that a simple model based on reaction-diffusion-advection (RDA) equation forced by realistic surface velocities and nutrients is skilled in reproducing the distributions of the surface phytoplankton chlorophyll in the tropical Pacific.
Scale-awareness in an eddy energy constrained mesoscale eddy parameterization
TL;DR: In this paper , a Gent-McWilliams-based version of GEOMETRIC, a mesoscale eddy parameterization that is constrained by a parameterized eddy energy budget, is shown to be scale-aware in its energetics.

Atmosphere-Ocean Dynamics
TL;DR: In this article, the authors describe how the Ocean-Atmosphere system is driven by transfer of properties between the atmosphere and the ocean. But they do not consider the effects of side boundaries.

TL;DR: In this article, the authors propose a quasigeostrophic motion of a Stratified Fluid on a Sphere (SFL) on a sphere, which is based on an Inviscid Shallow-Water Theory.

Isopycnal mixing in ocean circulation models
TL;DR: In this paper, a subgrid-scale form for mesoscale eddy mixing on isopycnal surfaces is proposed for use in non-eddy-resolving ocean circulation models.

Geographical Variability of the First Baroclinic Rossby Radius of Deformation
TL;DR: In this paper, the first baroclinic gravity-wave phase speed c1 and the Rossby radius of deformation l1 are computed from climatological average temperature and salinity profiles.
