  abstract = {A sigma coordinate ocean circulation model is employed to study flow
   trapped to a tall seamount in a periodic f-plane channel. In Part
   I, errors arising from the pressure gradient formulation in the steep
   topography/strong stratification limit are examined. To illustrate
   the error properties, a linearized adiabatic version of the model
   is considered, both with and without forcing, and starting from a
   resting state with level isopycnals. The systematic discretization
   errors from the horizontal pressure gradient terms are shown analytically
   to increase with steeper topography (relative to a fixed horizontal
   grid) and for stronger stratification (as measured by the Burger
   number). For an initially quiescent unforced ocean, the pressure
   gradient errors produce a spurious oscillating current that, at the
   end of 10 days, is approximately 1 cm s−1 in amplitude. The
   period of the spurious oscillation (about 0.5 days) is shown to be
   a consequence of the particular form of the pressure gradient terms
   in the sigma coordinate system. With the addition of an alongchannel
   diurnal forcing, resonantly generated seamount-trapped waves are
   observed to form. Error levels in these solutions are less than those
   in the unforced cases; spurious time-mean currents are several orders
   of magnitude less in amplitude than the resonant propagating waves.
   However, numerical instability is encountered in a wider range of
   parameter space. The properties of these resonantly generated waves
   is explored in detail in Part II of this study. Several new formulations
   of the pressure gradient terms are tested. Two of the formulations—constructed
   to have additional conservation properties relative to the traditional
   form of the pressure gradient terms (conservation of JEBAR and conservation
   of energy)—are found to have error properties generally similar
   to those of the traditional formulation. A corrected gradient algorithm,
   based upon vertical interpolation of the pressure field, has a dramatically
   reduced error level but a much more restrictive range of stable behavior.},

  journal = JC,
  year = {1997},
  volume = {10},
  pages = {1473-1486},
  abstract = {One open question in El Nin˜o–Southern Oscillation (ENSO) simulation
   and predictability is the role of random
   
   forcing by atmospheric variability with short correlation times, on
   coupled variability with interannual timescales.
   
   The discussion of this question requires a quantitative assessment
   of the stochastic component of the wind stress
   
   forcing. Self-consistent estimates of this noise (the stochastic forcing)
   can be made quite naturally in an empirical
   
   atmospheric model that uses a statistical estimate of the relationship
   between sea surface temperature (SST) and
   
   wind stress anomaly patterns as the deterministic feedback between
   the ocean and the atmosphere. The authors
   
   use such an empirical model as the atmospheric component of a hybrid
   coupled model, coupled to the GFDL
   
   ocean general circulation model. The authors define as residual the
   fraction of the Florida State University wind
   
   stress not explained by the empirical atmosphere run from observed
   SST, and a noise product is constructed by
   
   random picks among monthly maps of this residual.
   
   The impact of included or excluded noise is assessed with several
   ensembles of simulations. The model is
   
   run in coupled regimes where, in the absence of noise, it is perfectly
   periodic: in the presence of prescribed
   
   seasonal variability, the model is strongly frequency locked on a
   2-yr period; in annual average conditions it
   
   has a somewhat longer inherent ENSO period (30 months). Addition of
   noise brings an irregular behavior that
   
   is considerably richer in spatial patterns as well as in temporal
   structures. The broadening of the model ENSO
   
   spectral peak is roughly comparable to observed. The tendency to frequency
   lock to subharmonic resonances
   
   of the seasonal cycle tends to increase the broadening and to emphasize
   lower frequencies. An inclination to
   
   phase lock to preferred seasons persists even in the presence of noise-induced
   irregularity. Natural uncoupled
   
   atmospheric variability is thus a strong candidate for explaining
   the observed aperiodicity in ENSO time series.
   
   Model–model hindcast experiments also suggest the importance of atmospheric
   noise in setting limits to ENSO
   
   predictability.},

  journal = {Journal of Marine Systems},
  year = {2004},
  pages = {1-22},
  abstract = {We compare simulations of the injection of mantle helium-3 into the
   deep ocean from six global coarse resolution models which participated
   in the Ocean Carbon Model Intercomparison Project (OCMIP). We also
   discuss the results of a study carried out with one of the models,
   which examines the effect of the subgrid-scale mixing parameterization.
   These sensitivity tests provide useful information to interpret the
   differences among the OCMIP models and between model simulations
   and the data.
   
   We find that the OCMIP models, which parameterize subgrid-scale mixing
   using an eddy-induced velocity, tend to
   
   underestimate the ventilation of the deep ocean, based on diagnostics
   with d3He. In these models, this parameterization is implemented
   with a constant thickness diffusivity coefficient. In future simulations,
   we recommend using such a parameterization with spatially and temporally
   varying coefficients in order to moderate its effect on stratification.
   
   The performance of the models with regard to the formation of AABW
   confirms the conclusion from a previous evaluation with CFC-11. Models
   coupled with a sea-ice model produce a substantial bottom water formation
   in the Southern Ocean that tends to overestimate AABW ventilation,
   while models that are not coupled with a sea-ice model systematically
   underestimate the formation of AABW.
   
   We also analyze specific features of the deep 3He distribution (3He
   plumes) that are particularly well depicted in the data and which
   put severe constraints on the deep circulation. We show that all
   the models fail to reproduce a correct propagation of these plumes
   in the deep ocean. The resolution of the models may be too coarse
   to reproduce the strong and narrow currents in the deep ocean, and
   the models do not incorporate the geothermal heating that may also
   contribute to the generation of these currents. We also use the context
   of OCMIP-2 to explore the potential of mantle helium-3 as a tool
   to compare and evaluate modeled deep-ocean circulations. Although
   the source function of mantle helium is known with a rather large
   uncertainty, we find that the parameterization used for the injection
   of mantle helium-3 is sufficient to generate realistic results, even
   in the Atlantic Ocean where a previous pioneering study [J. Geophys.
   Res. 100 (1995) 3829] claimed this parameterization generates
   
   inadequate results. These results are supported by a multi-tracer
   evaluation performed by considering the simulated distributions of
   both helium-3 and natural 14C, and comparing the simulated tracer
   fields with available data.},

   locally and globally of tracer when the baroclinic and tracer time

  abstract = {The error in computing the pressure gradient force near steep topography
   using terms following (σ) coordinates is investigated in an
   ocean model using the family of vertical differencing schemes proposed
   by Arakawa and Suarez. The truncation error is estimated by substituting
   known buoyancy profiles into the finite difference hydrostatic and
   pressure gradient terms. The error due to “hydrostatic inconsistency,”
   which is not simply a space truncation error, is also documented.
   The results show that the pressure gradient error is spread throughout
   the water column, and it is sensitive to the vertical resolution
   and to the placement of the grid points relative to the vertical
   structure of the buoyancy field being modeled. Removing a reference
   state, as suggested for the atmosphere by Gary, reduces the truncation
   error associated with the two lowest vertical modes by a factor of
   2 to 3. As an example, the error in computing the pressure gradient
   using a standard 10-level primitive equation model applied to buoyancy
   profiles and topographic slopes typical of the California Current
   region corresponds to a false geostrophic current of the order of
   10–12 cm s−1. The analogous error in a hydrostatically
   consistent 30-level model with the reference state removed is about
   an order of magnitude smaller.},

   in treating the intersections of coordinate surfaces with the lower
   boundary. The purpose of this paper is to describe the θ-coordinate
   model we have developed and to demonstrate its potential through
   simulating the nonlinear evolution of a baroclinic wave.In the model
   we have developed, vertical discretization maintains important integral
   constraints, such as conservation of the angular momentum and total
   energy. In treating the intersections of coordinate surfaces with
   the lower boundary, we have followed the massless-layer approach
   in which the intersecting coordinate surfaces are extended along
   the boundary by introducing massless layers. Although this approach
   formally eliminates the intersection problem, it raises other computational
   problems. Horizontal discretization of the continuity and momentum
   equations in the model has been carefully designed to overcome these
   problems.Selected results from a 10-day integration with the 25-layer,
   β-plane version of the model are presented. It seems that the
   model can simulate the nonlinear evolution of a baroclinic wave and
   associated dynamical processes without major computational difficulties.},

  volume = {29},
  pages = {2945-2961},
  number = {11},
  abstract = {Numerous numerical simulations of basin-scale ocean circulation display
   a vast interior downwelling and a companion intense western boundary
   layer upwelling at midlatitude below the thermocline. These features,
   related to the so-called Veronis effect, are poorly rationalized
   and depart strongly from the classical vision of the deep circulation
   where upwelling is considered to occur in the interior. Furthermore,
   they significantly alter results of ocean general circulation models
   (OGCMs) using horizontal Laplacian diffusion. Recently, some studies
   showed that the parameterization for mesoscale eddy effects formulated
   by Gent and McWilliams allows integral quantities like the streamfunction
   and meridional heat transport to be free of these undesired effects.
   In this paper, an idealized OGCM is used to validate an analytical
   rationalization of the processes at work and help understand the
   physics. The results show that the features associated with the Veronis
   effect can be related quantitatively to three different width scales
   that characterize the baroclinic structure of the deep western boundary
   current. In addition, since one of these scales may be smaller than
   the Munk barotropic layer, usually considered to determine the minimum
   resolution and horizontal viscosity for numerical models, the authors
   recommend that it be taken into account. Regarding the introduction
   of the new parameterization, diagnostics in terms of heat balances
   underline some interesting similarities between local heat fluxes
   by eddy-induced velocities and horizontal diffusion at low and midlatitudes
   when a common large diffusivity (here 2000 m2 s−1) is used.
   The near-quasigeostrophic character of the flow explains these results.
   As a consequence, the response of the Eulerian-mean circulation is
   locally similar for runs using either of the two parameterizations.
   However, it is shown that the advective nature of the eddy-induced
   heat fluxes results in a very different effective circulation, which
   is the one felt by tracers.},

  abstract = {The large-scale processes preconditioning the winter deep-water formation
   in the northwestern Mediterranean Sea are investigated with a primitive
   equation numerical model where convection is parameterized by a non-penetrative
   convective adjustment algorithm. The ocean is forced by momentum
   and buoyancy fluxes that have the gross features of mean winter forcing
   found in the MEDOC area. The wind-driven barotropic circulation appears
   to be a major ingredient of the preconditioning phase of deep-water
   formation. After three months, the ocean response is dominated by
   a strong barotropic cyclonic vortex located under the forcing area,
   which fits the Sverdrup balance away from the northern coast. In
   the vortex center, the whole water column remains trapped under the
   forcing area all winter. This trapping enables the thermohaline forcing
   to drive deep-water formation efficiently. Sensitivity studies show
   that, β effect and bottom topography play a paramount role and
   confirm that deep convection occurs only in areas that combine a
   strong surface thermohaline forcing and a weak barotropic advection
   so that water masses are submitted to the negative buoyancy fluxes
   for a much longer time. In particular, the impact of the Rhône
   Deep Sea Fan on the barotropic circulation dominates the β effect:
   the barotropic flow is constrained to follow the bathymetric contours
   and the cyclonic vortex is shifted southward so that the fluid above
   the fan remains quiescent. Hence, buoyancy fluxes trigger deep convection
   above the fan in agreement with observations. The selection of the
   area of deep-water formation through the defection of the barotropic
   circulation by the topography seems a more efficient mechanism than
   those associated with the wind- driven barotropic vortex. This is
   due to its permanency, while the latter may be too sensitive to time
   and space variations of the forcing.},

   rather efficiently by mesoscale eddies and two-dimensional turbulence

   parcels are moved small distances in the neutral surface, they experience
   no buoyant restoring forces. By contrast, work would have to be done
   on a moving fluid parcel in order to keep it on a potential density
   surface. The differences between neutral surfaces and potential density
   surfaces are due to the variation of α/β with pressure
   (where α is the thermal expansion coefficient and β is
   the saline contraction coefficient). By regarding the equation of
   state of seawater as a function of salinity, potential temperature,
   and pressure, rather than in terms of salinity, temperature, and
   pressure, it is possible to quantify the differences between neutral
   surfaces and potential density surfaces. In particular, the spatial
   gradients of scalar properties (e.g., S, θ, tritium or potential
   vorticity) on a neutral surface can be quite different to the corresponding
   gradients in a potential density surface. For example, at a potential
   temperature of 4°C and a pressure of 1000 db, the lateral gradient
   of potential temperature in a potential density surface (referenced
   to sea level) is too large by between 50% and 350% (depending

   physically relevant gradient of potential temperature on the neutral
   surface. Three-examples of neutral surfaces are presented, based

  abstract = {Dissipation in numerical ocean models has two purposes: to simulate
   processes in which the friction is physically relevant and to prevent
   numerical instability by suppressing accumulation of energy in the
   smallest resolved scales. This study shows that even for the latter
   case the form of the friction term should be chosen in a physically
   consistent way. Violation of fundamental physical principles reduces
   the fidelity of the numerical solution, even if the friction is small.
   Several forms of the lateral friction, commonly used in numerical
   ocean models, are discussed in the context of shallow-water equations
   with nonuniform layer thickness. It is shown that in a numerical
   model tuned for the minimal dissipation, the improper form of the
   friction term creates finite artificial vorticity sources that do
   not vanish with increased resolution, even if the viscous coefficient
   is reduced consistently with resolution. An alternative numerical
   implementation of the no-slip boundary conditions for an arbitrary
   coast line is considered. It was found that the quality of the numerical
   solution may be considerably improved by discretization of the viscous
   stress tensor in such a way that the numerical boundary scheme approximates
   not only the stress tensor to a certain order of accuracy but also
   simulates the truncation error of the numerical scheme used in the
   interior of the domain. This ensures error cancellation during subsequent
   use of the elements of the tensor in the discrete version of the
   momentum equations, allowing for approximation of them without decrease
   in the order of accuracy near the boundary.},

   in conjunction with any vertical coordinate system and is easily

   in terms of a vertical integral of the Jacobian of density and depth
   with respect to the vertical computational coordinate. Finite difference
   approximations are made on the density field, consistent with piecewise
   linear and continuous fields, and accurate pressure gradients are
   obtained by vertically integrating the discrete Jacobian from sea
   surface.Two discrete schemes are derived and examined in detail:
   the first using standard centered differencing in the generalized
   vertical coordinate and the second using a vertical weighting such
   that the finite differences are centered with respect to the Cartesian
   z coordinate. Both schemes achieve second-order accuracy for any
   vertical coordinate system and are significantly more accurate than
   conventional schemes based on estimating the pressure gradients by
   finite differencing a previously determined pressure field.The standard
   Jacobian formulation is constructed to give exact pressure gradient
   results, independent of the bottom topography, if the buoyancy field
   varies bilinearly with horizontal position, x, and the generalized
   vertical coordinate, s, over each grid cell. Similarly, the weighted
   Jacobian scheme is designed to achieve exact results, when the buoyancy
   field varies linearly with z and arbitrarily with x, that is, b(x,z)
   = b0(x) + b1(x)z.When horizontal resolution cannot be made
   fine enough to avoid hydrostatic inconsistency, errors can be substantially
   reduced by the choice of an appropriate vertical coordinate. Tests
   with horizontally uniform, vertically varying, and with horizontally
   and vertically varying buoyancy fields show that the standard Jacobian
   formulation achieves superior results when the condition for hydrostatic
   consistency is satisfied, but when coarse horizontal resolution causes
   this condition to be strongly violated, the weighted Jacobian may

   Numerical consistency is investigated with respect to global energy
   conservation, depth-integrated momentum changes, and the representation
   of the bottom pressure torque. The performances of the numerical
   schemes are tested in prognostic integrations of an ocean model to
   demonstrate numerical accuracy and long-term integral stability.
   Two typical geometries, an isolated tall seamount and an unforced
   basin with sloping boundaries, are considered for the special case
   of no external forcing and horizontal isopycnals to test numerical
   accuracy. These test problems confirm that the proposed schemes yield
   accurate approximations to the pressure gradient force. Integral
   consistency conditions are verified and the energetics of the “advective
   elimination” of the pressure gradient error (Mellor et al)
   is considered.A large-scale wind-driven basin with and without topography
   is used to test the model’s long-term integral performance
   and the effects of bottom pressure torque on the transport in western
   boundary currents. Integrations are carried out for 10 years in each
   case and results show that the schemes are stable, and the steep
   topography causes no obvious numerical problems. A realistic meandering
   western boundary current is well developed with detached cold cyclonic
   and warm anticyclonic eddies as it extends across the basin. In addition,
   the results with topography show earlier separation and enhanced

   consistent with the fact that the ocean interior is nearly adiabatic.
   Gent and McWilliams have described a framework in which this can
   be approximated in z-coordinate primitive equation models by incorporating
   the effects of eddies on the buoyancy field through an eddy-induced
   velocity. It is also natural to base a parameterization on the simple
   picture of the mixing of potential vorticity in the interior and
   the mixing of buoyancy at the surface. The authors discuss the various
   constraints imposed by these two requirements and attempt to clarify
   the appropriate boundary conditions on the eddy-induced velocities
   at the surface. Quasigeostrophic theory is used as a guide to the
   simplest way of satisfying these constraints.},

  pages = {1171-1187},
  number = {5},
  abstract = {Leonard’s widely used QUICK advection scheme is, like the Bryan–Cox–Semtner
   ocean model, based on a control volume form of the advection equation.
   Unfortunately, in its normal form it cannot be used with the leapfrog–Euler
   forward time-stepping schemes used by the ocean model. Farrow and
   Stevens overcame the problem by implementing a predictor–corrector
   time-stepping scheme, but this is computationally expensive to run.
   The present paper shows that the problem can be overcome by splitting
   the QUICK operator into an O(δx2) advective term and a velocity
   dependent biharmonic diffusion term. These can then be time-stepped
   using the combined leapfrog and Euler forward schemes of the Bryan–Cox–Semtner
   ocean model, leading to a significant increase in model efficiency.
   A small change in the advection operator coefficients may also be
   made leading to O(δx4) accuracy. Tests of the improved schemes
   are carried out making use of a global eddy-permitting ocean model.
   Results are presented from cases where the schemes were applied to
   only the tracer fields and also from cases where they were applied
   to both the tracer and velocity fields. It is found that the new
   schemes have the most effect in the western boundary current regions,
   where, for example, the warm core of the Agulhas Current is no longer
   broken up by numerical noise.},
