 \chapter*{Abstract}
 
-SI$^3$ (Sea Ice modelling Integrated Initiative) is the sea ice engine of NEMO (Nucleus for European Modelling of the Ocean). It is adapted to regional and global sea ice and climate problems. It is intended to be a flexible tool for studying sea ice and its interactions with the other components of the Earth System over a wide range of space and time scales. SI$^3$ is based on the Arctic Ice Dynamics Joint EXperiment (AIDJEX) framework \citep{Coonetal74}, combining the ice thickness distribution framework, the conservation of horizontal momentum, an elastic-viscous plastic rheology, and energy-conserving halo-thermodynamics. Prognostic variables are the two-dimensional horizontal velocity field, ice volume, area, enthalpy, salt content, snow volume and enthalpy. In the horizontal direction, the model uses a curvilinear orthogonal grid. In the vertical direction, the model uses equally-spaced layers. In thickness space, the model uses thickness categories with prescribed boundaries. Various physical and numerical choices are available to describe sea ice physics. SI$^3$ is interfaced with the NEMO ocean engine, and, via the OASIS coupler, with several atmospheric general circulation models. It also supports two-way grid embedding via the AGRIF software.

- % This bibliography style file is intended for texts in ENGLISH
- % This is an author-year citation style bibliography. As such, it is
- % non-standard LaTeX, and requires a special package file to function properly.
- % Such a package is    natbib.sty   by Patrick W. Daly
- % The form of the \bibitem entries is
- %   \bibitem[Jones et al.(1990)]{key}...
- %   \bibitem[Jones et al.(1990)Jones, Baker, and Smith]{key}...
- % The essential feature is that the label (the part in brackets) consists
- % of the author names, as they should appear in the citation, with the year
- % in parentheses following. There must be no space before the opening
- % parenthesis!
- % With natbib v5.3, a full list of authors may also follow the year.
- % In natbib.sty, it is possible to define the type of enclosures that is
- % really wanted (brackets or parentheses), but in either case, there must
- % be parentheses in the label.
- % The \cite command functions as follows:
- %   \citet{key} ==>>                Jones et al. (1990)
- %   \citet*{key} ==>>               Jones, Baker, and Smith (1990)
- %   \citep{key} ==>>                (Jones et al., 1990)
- %   \citep*{key} ==>>               (Jones, Baker, and Smith, 1990)
- %   \citep[chap. 2]{key} ==>>       (Jones et al., 1990, chap. 2)
- %   \citep[e.g.][]{key} ==>>        (e.g. Jones et al., 1990)
- %   \citep[e.g.][p. 32]{key} ==>>   (e.g. Jones et al., p. 32)
- %   \citeauthor{key} ==>>           Jones et al.
- %   \citeauthor*{key} ==>>          Jones, Baker, and Smith
- %   \citeyear{key} ==>>             1990

 There are two means to specify the position of the thickness boundaries of ice categories. The first option (ln\_cat\_hfn) is to use a fitting function that places the category boundaries between 0 and 3$\overline h$, with $\overline h$ the expected mean ice thickness over the domain (namelist parameter rn\_himean), and with a greater resolution for thin ice (Fig. \ref{fig_dom_icecats}).

-The choice of ice categories is important, because it constraints the ability of the model to resolve the ice thickness distribution.

 With a fixed number of cores, the cost of the model linearly increases with the number of ice categories. Using $jpl=1$ single ice category is also much cheaper than with 5 categories, but seriously deteriorates the ability of the model to grow and melt ice. Indeed, thin ice thicknes faster than thick ice, and shrinks more rapidly as well. When nn\_virtual\_itd=1 ($jpl$ = 1 only), two parameterizations are activated to compensate for these shortcomings. Heat conduction and areal decay of melting ice are adjusted to closely approach the 5 categories case.

 \subsection{Scales, thermodynamics and dynamics}
-Because sea ice is much wider -- $\mathcal{O}$(100-1000 km) -- than thick -- $\mathcal{O}$(1 m) -- ice drift can be considered as purely horizontal: vertical motions around the hydrostatic equilibrium position are negligible. The same scaling argument justifies the assumption that heat exchanges are purely vertical\footnote{The latter assumption is probably less valid, because the horizontal scales of temperature variations are $\mathcal{O}$(10-100 m)}. It is on this basis that thermodynamics and dynamics are separated and rely upon different frameworks and sets of hypotheses: thermodynamics use the ice thickness distribution \citep{Thorndikeetal75} and the mushy-layer \citep{Worster92} frameworks, whereas dynamics assume continuum mechanics \citep[e.g.,][]{Lepparanta05}. Thermodynamics and dynamics interact by two means: first, advection impacts state variables; second, the horizontal momentum equation depends, among other things, on the ice state.

Yet important features, such as energy exchanges through the ice, quite non-linearly depend on ice thickness \citep{Maykut86}; whereas ice motion depends on the presence of open water, thin and thick ice at the very least, suggesting that subgrid-scale variations in ice properties must be accounted for, at least in a statistical fashion \citep{MaykutThorndike73}.

-Ice thermodynamics are formulated assuming that sea ice is covered by snow.

Snow is assumed to be fresh, with constant density and thermal conductivity. Sea ice is assumed to be a \textit{mushy layer}\footnote{Mushy layers are two-phase, two-component porous media.} \citep{Worster92} of constant density, made of pure ice and brine in thermal equilibrium, related by a linear liquidus relationship \citep{BitzLipscomb99}. A vertically-averaged bulk salinity $S_l$ uniquely characterizes brine fraction for each thickness category, and changes through  time from a simple parametrization of brine drainage. The linear vertical salinity profile ($S^*_{kl}$) is reconstructed from the vertical mean \citep{Vancoppenolleetal09b}. The diffusion of heat affects the vertical temperature profile, discretized on a unique layer of snow and multiple ice layers (typically 2-5) for each category, whereas thermal properties depend on local brine fraction. Growth and melt rates are computed, also for each ice category. The choice of the main thermodynamic constants  is described in Tab. \ref{PhysicalConstants_table}.

The latter holds provided the drift ice particles are much larger than single ice floes, and much smaller than typical gradient scales. This compromise is rarely achieved in practice \citep{Lepparanta05}.

The most important term in the momentum equation is internal stress. We follow the viscous-plastic (VP) rheological framework \citep{Hibler79}, assuming that sea ice has no tensile strength but responds to compressive and shear deformations in a plastic way. In practice, the elastic-viscous-plastic (EVP) technique of  \citep{Bouillonetal13} is used, more convient numerically than VP.  It is well accepted that the VP rheology and its relatives are the minimum complexity to get reasonable ice drift patterns \citep{Kreyscheretal00}, but fail at generating the observed deformation patterns \citep{Girardetal09}. This is a long-lasting problem: what is the ideal rheological model for sea ice and how it should be applied are still being debated \citep[see, e.g.][]{Weiss13}.

-The scheme of  \cite{Prather86} explicitly computes the conservation of second-order moments of the spatial distribution of global sea ice state variables. This scheme preserves positivity of the transported variables and is practically non-diffusive. It is also computationally expensive, however it allows to localize the ice edge quite accurately. As the scheme is conditionally stable, the time step is split into two parts if the ice drift is too fast, based on the CFL criterion.

 State variables per unit grid cell area are first multiplied by grid cell area. Then, for each state variable, the 0$^{th}$ (mean), 1$^{st}$ (x, y) and 2$^{nd}$ (xx, xy, yy) order moments of the spatial distribution are transported. At 1st time step, all moments are zero (if prescribed initial state); or read from a restart file, and then evolve through the course of the run. Therefore, for each global variable, 5 additional tracers have to be kept into memory and written in the restart file, which significantly increases the required memory. Advection following x and y are computed independently. The succession order of x- and y- advection is reversed every day.

SI$^3$ merges the capabilities of the 3 formerly used NEMO sea ice models (CICE, GELATO and LIM). The \textbf{3} in SI$^3$ refers to the three formerly used sea ice models. It also refers to linkages between 3 different media (ocean, ice, snow). The model can be spelt 'SI3' in situations where the superscript could be problematic (i.e., within code and svn repository etc.) The model name would be pronounced as 'si-cube' for short (or 'sea ice cubed' for slightly longer).

-%There are limitations to the applicability of models such as SI$^3$.

Second, one must remember that our current knowledge of sea ice is not as complete as for the ocean: there are no fundamental equations such as Navier Stokes equations for sea ice. Besides, important features and processes span widely different scales, such as brine inclusions (1 $\mu$m-1 mm) \citep{PerovichGow96}, horizontal thickness variations (1 m-100 km) \citep{Percivaletal08}, deformation and fracturing (10 m-1000 km) \citep{Marsanetal04}. These impose complicated and often subjective subgrid-scale treatments. All in all, there is more empirism in sea ice models than in ocean models.
