TLDR
In this article, it is shown that when allowing the flow to adjust to non-hydrostatic pressure, the growth of the flow due to internal pressure errors may be strongly affected.About:

Correction and commentary for Ocean forecasting in terrain-following coordinates: Formulation and skill assessment of the regional ocean modeling system by Haidvogel et al., J. Comp. Phys. 227, pp. 3595-3624
TL;DR: The model equations appearing in H2008, Section 2.1 (taken from an earlier article, Haidvogel et al. (2000) [3]) are not entirely consistent with the actual equations solved in the ROMS code, resulting in contradictions within H2008 itself.

Algorithm for non-hydrostatic dynamics in the Regional Oceanic Modeling System
TL;DR: In this article, a non-hydrostatic algorithm for the Regional Oceanic Modeling System (ROMS) is proposed, which is based on a decomposition technique for hydrostatic and non hydrostatic pressure.

The numerics of hydrostatic structured-grid coastal ocean models: state of the art and future perspectives
TL;DR: The state of the art of the numerics of hydrodynamic non-hydrostatic structured-grid coastal ocean models is reviewed in this paper, with a focus on the specific requirements for local ocean models.

Implementation of a direct nonhydrostatic pressure gradient discretisation into a layered ocean model
Knut Klingbeil,Hans Burchard +1 more
TL;DR: To demonstrate the necessary modifications to an explicit mode-splitting hydrostatic model kernel, the extension of the General Estuarine Transport Model (GETM) is outlined and validation indicates the nonhydrostatic capability of the extended GETM.
Journal ArticleDOI
Assessment of non-hydrostatic ocean models using laboratory scale problems
TL;DR: In this article, a non-hydrostatic z-coordinate model was used to study lock release gravity currents in a flat bottom tank, and the propagation and breaking of an internal solitary wave in a tank with a sloping bottom.

Numerical heat transfer and fluid flow
TL;DR: In this article, the authors focus on heat and mass transfer, fluid flow, chemical reaction, and other related processes that occur in engineering equipment, the natural environment, and living organisms.
Journal ArticleDOI
General circulation experiments with the primitive equations
TL;DR: In this article, an extended period numerical integration of a baroclinic primitive equation model has been made for the simulation and the study of the dynamics of the atmosphere's general circulation, and the solution corresponding to external gravitational propagation is filtered by requiring the vertically integrated divergence to vanish identically.

Development of a turbulence closure model for geophysical fluid problems
George L. Mellor,Tetsuji Yamada +1 more
TL;DR: The second-moment turbulent closure hypothesis has been applied to geophysical fluid problems since 1973, when genuine predictive skill in coping with the effects of stratification was demonstrated as discussed by the authors.
