“…The Kurihara method (Kurihara et al 1979) has been used by several authors to enforce conservation (Kurihara and Bender 1980;Ginis et al 1998). It is important to note that it applies to a model with all variables cell-centered.…”

International audienceLocal mesh refinement features have now been added to a number of numerical ocean models. In its crudest form, a high-resolution grid is embedded (or nested) in a coarse-resolution grid, which covers the entire domain, and the two grids interact. The aim of this paper is to review existing two-way grid embedding algorithms. The basic algorithms and specificities related to ocean modelling are first described. Then, we address several important issues: conservation properties, design of interpolation/restriction operators, and noise control techniques

“…Nesting is not restricted to combining two di erent simulations. More than two di erent resolutions can be combined, as in Ginis et al [109]. An alternative to increasing the spatial resolution via nesting is to use variable mesh spacing in the di erent directions like in Staniforth and Mitchell [280], or to adjust the mesh with the help of a coordinate transformation, as in Dietachmeyer and Droegemeier [75].…”

Numerical Weather Prediction (NWP) is in a period of transition. As resolutions increase, global models are moving towards fully nonhydrostatic dynamical cores, with the local and global models using the same governing equations; therefore we have reached a point where it will be necessary to use a single model for both applications. The new dynamical cores at the heart of these unified models are designed to scale e ciently on clusters with hundreds of thousands or even millions of CPU cores and GPUs. Operational and research NWP codes currently use a wide range of numerical methods: finite di erences, spectral transform, finite volumes and, increasingly, finite/spectral elements and discontinuous Galerkin, which constitute element-based Galerkin (EBG) methods. Due to their important role in this transition, will EBGs be the dominant power behind NWP in the next 10 years, or will they just be one of many methods to choose from? One decade after the review of numerical methods for atmospheric modeling by Steppeler et al. (2003) [Review of numerical methods for nonhydrostatic weather prediction models Meteorol. Atmos. Phys. 82, 2003], this review discusses EBG methods as a viable numerical approach for the next-generation NWP models. One well-known weakness of EBG methods is the generation of unphysical oscillations in advection-dominated flows; special attention is hence devoted to dissipation-based stabilization methods. Since EBGs are geometrically flexible and allow both conforming and non-conforming meshes, as well as grid adaptivity, this review is concluded with a short overview of how mesh generation and dynamic mesh refinement are becoming as important for atmospheric modeling as they have been for engineering applications for many years.

“…The local model POM with high resolution [9] is a modification of the Australian version [10] of a three-dimensional numerical hydrodynamic model of ocean circulation of the Princeton University [11] adapted to the Black Sea conditions. POM is based on the total system of hydrodynamics equations with approximations of Boissinesque and hydrostatics, and s-transfor-mation of the vertical coordinate.…”

Operational monitoring system is developed to automatize the process of diagnosis and forecast of hydrological fields of marine environment in the Sevastopol Black Sea region based on the local hydrodynamical model POM. The initial and boundary conditions for the local model are set from the basin model of the Black Sea dynamics. The data obtained by SKIRON Regional Forecast Center of Athens University is applied as the atmospheric effect. For the parameterization of vertical mixing in local circulation model POM turbulence model based on turbulence hypotheses of Rott -Kolmogorov and generalized by Mellor and Yamada in the case of a stratified flow is included. The model takes into consideration the penetration of the short-wave solar radiation into the water column. System automation is implemented using the CalcMan software package which is an own development of Marine Hydrophysical Institute. The output fields are accessible in the NetCDF format with horizontal spatial resolution constituting 1 km, vertical resolution -18 irregular levels from 2.5 to 1000 m and time resolution -3 hr. The system provides a possibility of daily updating the forecast data. Based on the THREDDS server, the specialized visualization subsystem is installed and configured to visualize and disseminate simulations results. Its user-friendly interface allows a server-side analysis of all the forecasted fields, permits to construct horizontal and vertical sections, vertical profiles and time series, to create animated pictures without downloading the data to a client's side. OPENDAP and NetcdfSubset interfaces are used for disseminating data in a digital form.
