    5050This results in a dissipatively dominant (\ie hyper-diffusive) truncation error

     52The overall performance of the advection scheme is similar to that reported in \cite{farrow.stevens_JPO95}. 
    5353It is a relatively good compromise between accuracy and smoothness. 
    5454It is not a \emph{positive} scheme meaning false extrema are permitted but 
     
    6565the second term which is the diffusive part of the scheme, is evaluated using the \textit{before} velocity 
    6666(forward in time). 
    67 This is discussed by \citet{Webb_al_JAOT98} in the context of the Quick advection scheme. 
     67This is discussed by \citet{webb.de-cuevas.ea_JAOT98} in the context of the Quick advection scheme. 
    6868UBS and QUICK schemes only differ by one coefficient. 
    69 Substituting 1/6 with 1/8 in (\autoref{eq:tra_adv_ubs}) leads to the QUICK advection scheme \citep{Webb_al_JAOT98}. 
     69Substituting 1/6 with 1/8 in (\autoref{eq:tra_adv_ubs}) leads to the QUICK advection scheme \citep{webb.de-cuevas.ea_JAOT98}. 
    7070This option is not available through a namelist parameter, since the 1/6 coefficient is hard coded. 
    7171Nevertheless it is quite easy to make the substitution in \mdl{traadv\_ubs} module and obtain a QUICK scheme.

     510\citep{griffies_JPO98} introduces another way to implement the eddy induced advection, the so-called skew form. 
    511511It is based on a transformation of the advective fluxes using the non-divergent nature of the eddy induced velocity. 
    512512For example in the (\textbf{i},\textbf{k}) plane, the tracer advective fluxes can be transformed as follows: 
     
    574574The horizontal component reduces to the one use for an horizontal laplacian operator and 
    575575the vertical one keeps the same complexity, but not more.

    5353  giving an almost pure horizontal diffusive tracer flux within the mixed layer.

    194194\subsection{Expression of the skew-flux in terms of triad slopes}

    473473 
    474474To complete the discretization we now need only specify the triad volumes $_i^k\mathbb{V}_{i_p}^{k_p}$. 
    475 \citet{Griffies_al_JPO98} identifies these $_i^k\mathbb{V}_{i_p}^{k_p}$ as the volumes of the quarter cells, 
     475\citet{griffies.gnanadesikan.ea_JPO98} identifies these $_i^k\mathbb{V}_{i_p}^{k_p}$ as the volumes of the quarter cells, 
    476476defined in terms of the distances between $T$, $u$,$f$ and $w$-points. 
    477477This is the natural discretization of \autoref{eq:cts-var}. 
     
    685685As discussed in \autoref{subsec:LDF_slp_iso}, 
    686686iso-neutral slopes relative to geopotentials must be bounded everywhere, 
    687 both for consistency with the small-slope approximation and for numerical stability \citep{Cox1987, Griffies_Bk04}. 
     687both for consistency with the small-slope approximation and for numerical stability \citep{cox_OM87, griffies_bk04}. 
    688688The bound chosen in \NEMO is applied to each component of the slope separately and 
    689689has a value of $1/100$ in the ocean interior. 
     
    859859\footnote{ 
    860860  To ensure good behaviour where horizontal density gradients are weak, 
    861   we in fact follow \citet{Gerdes1991} and

    863863} 
     
    865865This approach is similar to multiplying the iso-neutral diffusion coefficient by 
    866866$\tilde{r}_{\mathrm{max}}^{-2}\tilde{r}_i^{-2}$ for steep slopes, 
    867 as suggested by \citet{Gerdes1991} (see also \citet{Griffies_Bk04}). 
     867as suggested by \citet{gerdes.koberle.ea_CD91} (see also \citet{griffies_bk04}).

    926926However, when \np{ln\_traldf\_triad} is set true, 
    927 \NEMO instead implements eddy induced advection according to the so-called skew form \citep{Griffies_JPO98}. 
     927\NEMO instead implements eddy induced advection according to the so-called skew form \citep{griffies_JPO98}. 
    928928It is based on a transformation of the advective fluxes using the non-divergent nature of the eddy induced velocity. 
    929929For example in the (\textbf{i},\textbf{k}) plane, 
     
    11391139it is equivalent to a horizontal eiv (eddy-induced velocity) that is uniform within the mixed layer 
    11401140\autoref{eq:eiv_v}. 
    1141 This ensures that the eiv velocities do not restratify the mixed layer \citep{Treguier1997,Danabasoglu_al_2008}.

    119119%In practice, \autoref{eq:ldfslp_iso} is of little help in evaluating the neutral surface slopes. Indeed, for an unsimplified equation of state, the density has a strong dependancy on pressure (here approximated as the depth), therefore applying \autoref{eq:ldfslp_iso} using the $in situ$ density, $\rho$, computed at T-points leads to a flattening of slopes as the depth increases. This is due to the strong increase of the $in situ$ density with depth.

    849849The response to such a velocity field often leads to numerical dispersion effects.

     878\citet{haney_JPO91} and \citet{beckmann.haidvogel_JPO93} have given estimates of the magnitude of this truncation error. 
    879879It depends on topographic slope, stratification, horizontal and vertical resolution, the equation of state, 
    880880and the finite difference scheme. 
     
    884884The large-scale slopes require high horizontal resolution, and the computational cost becomes prohibitive. 
    885885This problem can be at least partially overcome by mixing $s$-coordinate and 
    886 step-like representation of bottom topography \citep{Gerdes1993a,Gerdes1993b,Madec_al_JPO96}. 
     886step-like representation of bottom topography \citep{gerdes_JGR93*a,gerdes_JGR93*b,madec.delecluse.ea_JPO96}.

    888888a realistic bottom topography: 
     
    904904In contrast, the ocean will stay at rest in a $z$-model. 
    905905As for the truncation error, the problem can be reduced by introducing the terrain-following coordinate below

    10051005The resulting lateral diffusive and dissipative operators are of second order. 
    10061006Observations show that lateral mixing induced by mesoscale turbulence tends to be along isopycnal surfaces

     1007(or more precisely neutral surfaces \cite{mcdougall_JPO87}) rather than across them.

    10091009the `lateral' direction is the horizontal, \ie the lateral mixing is performed along geopotential surfaces. 
     
    10161016both horizontal and isoneutral operators have no effect on mean (\ie large scale) potential energy whereas

    6565The time stepping used for processes other than diffusion is the well-known leapfrog scheme 
    66 \citep{Mesinger_Arakawa_Bk76}. 
     66\citep{mesinger.arakawa_bk76}. 
    6767This scheme is widely used for advection processes in low-viscosity fluids. 
    6868It is a time centred scheme, \ie the RHS in \autoref{eq:STP} is evaluated at time step $t$, the now time step. 
     
    8080To prevent it, the leapfrog scheme is often used in association with a Robert-Asselin time filter 
    8181(hereafter the LF-RA scheme). 
    82 This filter, first designed by \citet{Robert_JMSJ66} and more comprehensively studied by \citet{Asselin_MWR72}, 
     82This filter, first designed by \citet{robert_JMSJ66} and more comprehensively studied by \citet{asselin_MWR72},

    8484\begin{equation} 
     
    8989$\gamma$ is initialized as \np{rn\_atfp} (namelist parameter). 
    9090Its default value is \np{rn\_atfp}~\forcode{= 10.e-3} (see \autoref{sec:STP_mLF}), 
    91 causing only a weak dissipation of high frequency motions (\citep{Farge1987}).

    9292The addition of a time filter degrades the accuracy of the calculation from second to first order. 
    9393However, the second order truncation error is proportional to $\gamma$, which is small compared to 1.
