6 | \NEMO\ (``Nucleus for European Modelling of the Ocean'') is a framework of ocean-related engines. |
---|
7 | It is intended to be a flexible tool for studying the ocean dynamics and thermodynamics (``blue ocean''), |
---|
8 | as well as its interactions with the components of the Earth climate system over |
---|
9 | a wide range of space and time scales. |
---|
10 | Within \NEMO, the ocean engine is interfaced with a sea-ice model (\SIcube\ or |
---|
11 | \href{http://github.com/CICE-Consortium/CICE}{CICE}), |
---|
12 | passive tracers and biogeochemical models (\TOP) and, |
---|
13 | via the \href{http://portal.enes.org/oasis}{OASIS} coupler, |
---|
14 | with several atmospheric general circulation models. |
---|
15 | It also supports two-way grid embedding by means of the \href{http://agrif.imag.fr}{AGRIF} software. |

17 | %% Specific part |
---|
18 | The primitive equation model is adapted to regional and global ocean circulation problems down to |
---|
19 | kilometric scale. |
---|
20 | Prognostic variables are the three-dimensional velocity field, a non-linear sea surface height, |
---|
21 | the \textit{Conservative} Temperature and the \textit{Absolute} Salinity. |
---|
22 | In the horizontal direction, the model uses a curvilinear orthogonal grid and |
---|
23 | in the vertical direction, a full or partial step $z$-coordinate, or $s$-coordinate, or |
---|
24 | a mixture of the two. |
---|
25 | The distribution of variables is a three-dimensional Arakawa C-type grid. |
---|
26 | Various physical choices are available to describe ocean physics, |
---|
27 | so as various HPC functionalities to improve performances. |
