Journal ArticleDOI
TL;DR: Coordinated Ocean-ice Reference Experiments (COREs) as mentioned in this paper is a tool to explore the behaviour of global ocean-ice models under forcing from a common atmospheric dataset, which is suitable for our purposes, even though its evaluation originally focussed more on the ocean than on the sea ice.

Journal ArticleDOI
TL;DR: In this article, a new version of the Louvain-la-Neuve sea ice model LIM3 is described and its results arc, compared with observations, and a hindcast of the Arctic and Antarctic sea ice packs, forced by a combination of daily NCEP/NCAR reanalysis data and various climatologies.

Journal ArticleDOI
TL;DR: In this paper, the elastic-viscous-plastic (EVP) sea ice rheology has been introduced in the large-scale Louvain-la-Neuve sea-ice Model, version 2 (LIM2), and its performance has been evaluated.

181 citations


Journal ArticleDOI
TL;DR: In this article, a finite element dynamic-thermodynamic sea ice model is developed and coupled to the ocean component, which is based on the Finite Element model of the North Atlantic (FENA) but has been substantially updated and extended.

Journal ArticleDOI
TL;DR: In this article, the authors identify a crucial numerical problem in sigma coordinate models, leading to unacceptable spurious diapycnal mixing and propose RSUP3, which is a modified version of the third-order up-wind advection scheme.

Journal ArticleDOI
TL;DR: In this paper, the authors employ a modified POD theory to incorporate a limited number of measurements in reconstructing the velocity and temperature fields, and study systematically the corresponding reconstruction errors as a function of the sensor location, number of sensors, and number of POD modes.

Journal ArticleDOI
TL;DR: In this paper, a linear programming (LP) procedure has been proposed to deal with the problem of horizontal pressure gradient (HPG) error in large basin and coastal seas simulations, and the success of the procedure in alleviating HPG error is gauged in comparison with two implementations of the Shapiro filter, the Mellor-Ezer-Oey (1994) algorithm (MEO), and the recently proposed procedure of Martinho and Batteen (MB).

Journal ArticleDOI
TL;DR: In this paper, a simple analytic representation for the depth profile of turbulent dissipation is proposed under the assumption that the near bottom wavefield is dominated by a baroclinic tide.

Journal ArticleDOI
TL;DR: In this paper, the authors add accepted version to spiral, Elsevier says ok while mandate not enforced, but the accepted version is not included in the published version of the spiral, so it cannot be used.
