Oceanic vertical mixing: a review and a model with a nonlocal boundary layer parameterization
- W. Large, J. McWilliams, S. Doney
- Geology
- 1 November 1994
If model parameterizations of unresolved physics, such as the variety of upper ocean mixing processes, are to hold over the large range of time and space scales of importance to climate, they must be… Expand
The regional oceanic modeling system (ROMS): a split-explicit, free-surface, topography-following-coordinate oceanic model
- Alexander F. Shchepetkin, J. McWilliams
- Mathematics
- 2005
Abstract The purpose of this study is to find a combination of optimal numerical algorithms for time-stepping and mode-splitting suitable for a high-resolution, free-surface, terrain-following… Expand
Isopycnal mixing in ocean circulation models
- P. Gent, J. McWilliams
- Geology
- 1990
Abstract A subgrid-scale form for mesoscale eddy mixing on isopycnal surfaces is proposed for use in non-eddy-resolving ocean circulation models. The mixing is applied in isopycnal coordinates to… Expand
Parameterizing eddy-induced tracer transports in ocean circulation models
- P. Gent, J. Willebrand, T. McDougall, J. McWilliams
- Physics
- 1 April 1995
Abstract It is shown that the effects of mesoscale eddies on tracer transports can be parameterized in a large-scale model by additional advection and diffusion of tracers. Thus, tracers are advected… Expand
Langmuir turbulence in the ocean
- J. McWilliams, P. Sullivan, C. Moeng
- Physics
- 10 March 1997
Solutions are analysed from large-eddy simulations of the phase-averaged
equations for oceanic currents in the surface planetary boundary layer
(PBL), where the averaging is over high-frequency… Expand
Mesoscale to Submesoscale Transition in the California Current System. Part I: Flow Structure, Eddy Flux, and Observational Tests
- X. Capet, J. McWilliams, M. J. Molemaker, A. F. Shchepetkin
- Geology
- 2008
In computational simulations of an idealized subtropical eastern boundary upwelling current system, similar to the California Current, a submesoscale transition occurs in the eddy variability as the… Expand
North Pacific Gyre Oscillation links ocean climate and ecosystem change
- E. Lorenzo, N. Schneider, +9 authors P. Rivière
- Environmental Science
- 1 April 2008
Decadal fluctuations in salinity, nutrients, chlorophyll, a variety of zooplankton taxa, and fish stocks in the Northeast Pacific are often poorly correlated with the most widely-used index of… Expand
A method for computing horizontal pressure‐gradient force in an oceanic model with a nonaligned vertical coordinate
- Alexander F. Shchepetkin, J. McWilliams
- Mathematics
- 1 March 2003
[1] Discretization of the pressure-gradient force is a long-standing problem in terrain-following (or σ) coordinate oceanic modeling. When the isosurfaces of the vertical coordinate are not aligned… Expand
Open boundary conditions for long-term integration of regional oceanic models
- P. Marchesiello, J. McWilliams, Alexander F. Shchepetkin
- Geology
- 2001
Regional oceanic models can be developed and used efficiently for the investigation of regional and coastal domains, provided a satisfactory prescription for the open boundary conditions (OBCs) is… Expand
Ocean forecasting in terrain-following coordinates: Formulation and skill assessment of the Regional Ocean Modeling System
- D. Haidvogel, H. Arango, +17 authors John Wilkin
