6 | The ocean engine of NEMO (Nucleus for European Modelling of the Ocean) is a primitive equation model adapted to |
7 | regional and global ocean circulation problems. |
8 | It is intended to be a flexible tool for studying the ocean and its interactions with the others components of |
9 | the earth climate system over a wide range of space and time scales. |
10 | |
11 | Prognostic variables are the three-dimensional velocity field, a non-linear sea surface height, |
12 | the \textit{Conservative} Temperature and the \textit{Absolute} Salinity. |
13 | In the horizontal direction, the model uses a curvilinear orthogonal grid and in the vertical direction, |
14 | a full or partial step $z$-coordinate, or $s$-coordinate, or a mixture of the two. |
15 | The distribution of variables is a three-dimensional Arakawa C-type grid. |
16 | Various physical choices are available to describe ocean physics, including TKE, and GLS vertical physics. |
17 | |
18 | Within NEMO, the ocean is interfaced with a sea-ice model (SI$^3$) |
19 | %or \href{https://github.com/CICE-Consortium/CICE}{CICE}), |
20 | passive tracer and biogeochemical models (TOP-PISCES) and, |
21 | via the \href{https://portal.enes.org/oasis}{OASIS} coupler, with several atmospheric general circulation models. |
22 | It also support two-way grid embedding via the \href{http://agrif.imag.fr}{AGRIF} software. |
