TL;DR: OPA as discussed by the authors is a primitive equation model of both the regional and global ocean circulation, which is intended to be a flexible tool for studying ocean and its interactions with the others components of the earth climate system (atmosphere, sea-ice, biogeochemical tracers,...) over a wide range of space and time scale.

TL;DR: A semi-analytical method is presented for constructing a global orthogonal curvilinear ocean mesh which has no singularity point inside the computational domain since the mesh poles are moved to land points and the Bering Strait can be opened without specific treatment.

TL;DR: In this paper, the authors used the mixed open boundary algorithm, which has both a radiation condition and a relaxation to climatology, to analyze the radiation phase velocities calculated within the algorithm, and showed that both the eastern and western boundaries have a similar behavior, regardless of the preferred directions for advection (mainly eastward) and wave propagation.

TL;DR: In this paper, a strong westerly wind event (WWE) occurred in the western equatorial Pacific prior to the 1997-1998 El Nino event and produced downwelling Kelvin waves that interacted non linearly with the surface temperature, salinity and zonal current fronts located at the eastern edge of the warm-fresh pool (EEWP).

TL;DR: In this article, two transient CO 2 experiments using two coupled general circulation models developed by the French GASTON group have been realized using the same methodology, and the main features of the present climate are reasonably well captured by both coupled models in the control simulations, although the biases are not the same.
