6\chapter*{Abstract / R\'{e}sum\'{e}}
11The ocean engine of NEMO (Nucleus for European Modelling of the Ocean) is a primitive
12equation model adapted to regional and global ocean circulation problems. It is intended to
13be a flexible tool for studying the ocean and its interactions with the others components of
14the earth climate system over a wide range of space and time scales.
15Prognostic variables are the three-dimensional velocity field, a non-linear sea surface height,
16the \textit{Conservative} Temperature and the \textit{Absolute} Salinity.
17In the horizontal direction, the model uses a curvilinear orthogonal grid and in the vertical direction,
18a full or partial step $z$-coordinate, or $s$-coordinate, or a mixture of the two.
19The distribution of variables is a three-dimensional Arakawa C-type grid.
20Various physical choices are available to describe ocean physics, including TKE, and GLS vertical physics.
21Within NEMO, the ocean is interfaced with a sea-ice model (LIM or CICE), passive tracer and
22biogeochemical models (TOP) and, via the OASIS coupler, with several atmospheric general circulation models.
23It also support two-way grid embedding via the AGRIF software.

28Le moteur oc\'{e}anique de NEMO (Nucleus for European Modelling of the Ocean) est un
29mod\`{e}le aux \'{e}quations primitives de la circulation oc\'{e}anique r\'{e}gionale et globale.
30Il se veut un outil flexible pour \'{e}tudier sur un vaste spectre spatiotemporel l'oc\'{e}an et ses
31interactions avec les autres composantes du syst\`{e}me climatique terrestre.
32Les variables pronostiques sont le champ tridimensionnel de vitesse, une hauteur de la mer
33lin\'{e}aire, la Temp\'{e}erature Conservative et la Salinit\'{e} Absolue.
34La distribution des variables se fait sur une grille C d'Arakawa tridimensionnelle utilisant une
35coordonn\'{e}e verticale $z$ \`{a} niveaux entiers ou partiels, ou une coordonn\'{e}e s, ou encore
36une combinaison des deux. Diff\'{e}rents choix sont propos\'{e}s pour d\'{e}crire la physique
37oc\'{e}anique, incluant notamment des physiques verticales TKE et GLS. A travers l'infrastructure
38NEMO, l'oc\'{e}an est interfac\'{e} avec des mod\`{e}les de glace de mer (LIM ou CICE),
39de biog\'{e}ochimie marine et de traceurs passifs, et, via le coupleur OASIS, \`{a} plusieurs
40mod\`{e}les de circulation g\'{e}n\'{e}rale atmosph\'{e}rique.
41Il supporte \'{e}galement l'embo\^{i}tement interactif de maillages via le logiciel AGRIF.
