Analysis of the barotropic model of the subtropical gyre in the ocean for finite Reynolds numbers. Part I

Eddies and friction : removal of vorticity from the wind-driven gyre

“…These counter-rotating gyres are present in the figures of Holland and Lin (1975), Kamenkovich et al (1995), and Sheremet et al (1995), but are significantly weaker than those present here and go uncommented upon in the text of those papers. Greatbatch and Nadiga (1999) and Holm and Nadiga (submitted 2002) were able to roughly parameterize these counter-rotating regions with various schemes for homogenization of absolute vorticity.…”

“…time-dependent and steady-state calculations with differing boundary conditions all demonstrate this behavior (Ierley and Sheremet (1995), Kamenkovich et al (1995), Sheremet et al (1995), Sheremet et al (1997)). These inertially-dominated solutions occur at modest inertia to friction ratios, leading one to wonder what occurs in the ocean where the friction is considered to be much smaller than the inertia, yet the ocean is strongly western-intensified with inertial western boundary currents and a relatively non-inertial interior.…”

Dynamics of nonlinear cross-equatorial flow in the deep ocean

“…More recent studies (e.g., (1987), Kamenkovich et al (1995), ) have extended the study to include very nonlinear flows. These authors also find a break-down of the steady laminar Munk boundary layer and for particularly strong nonlinearity, the development of an inertial recirculation in one region of the basin.…”

Low-frequency variability of a two-layer ocean forced by periodic winds

“…the down-gradient diffusion of potential vorticity, has been one of the important subjects for improving coarse-grid models (Young, 1987;Gent and McWilliams, 1990). Kamenkovich et al (1995), MB97: Meacham and Berloff (1997), BM97: Berloff and Meacham (1997), BM98: Meacham (1998), S04: Sakamoto (2004). † Free-slip at the eastern and western boundaries and no-slip at the northern and southern boundaries.…”
