Showing papers in "Ocean Modelling in 2000"

TL;DR: In this article, the authors present some research developments in primitive equation ocean models which could impact the ocean component of realistic global coupled climate models aimed at large-scale, low frequency climate simulations and predictions.

TL;DR: In this article, a priori estimates for water temperature, heat flux and currents were made for a pre-expedition planning, based on prior knowledge of lake Vostok.

TL;DR: The purpose of the paper is to extend the one-to-one correspondence between the two analysis schemes by proposing a heuristic statistical error expression for the VIM.

TL;DR: An incremental method is presented to generate automatically boundary-fitted Delaunay triangulations of the global ocean that takes into account Earth curvature and allows local mesh refinement in order to resolve topological or dynamical features like midocean ridges or western boundary currents.

TL;DR: In this paper, a modified version of the Stommel gyre test is presented, in which the underlying grid is rotated relative to the gyre, such that the western boundary falls at 45° to the principal grid axes.

TL;DR: In this article, a theoretical argument is given that, in an ocean with sloping sidewalls, this geostrophic balance results in bottom pressure torques which balance the wind stress curl at each latitude, suggesting that the dynamics within a western boundary current may be essentially inviscid.

TL;DR: A “reduced” grid is applied to a three-dimensional primitive equation ocean-climate model to keep the longitudinal width of model cells as uniform as possible, and results of model runs are presented showing small effects on the solution and sizable improvements to the execution time.

TL;DR: A simplified box model of the cooling of a salt-stratified ocean is analyzed analytically and numerically in this paper, where the authors show that increased cooling produces much greater flow rate; consequentially temperature increases rather than decreases in the small basin.

TL;DR: In this article, the authors show that extrapolating zonal-average temperature and salinity fields forward in time can shorten integration times by a factor of two to three, but do not yield an exact solution.
