Abstract:
There is a need in energy-poor sub-Saharan Africa for a system to manage energy more efficiently and effectively both within and between countries. An approach that has been proven in other parts of the world to facilitate this is super grids. With their interconnection and information management systems, super grids can contribute to the increasingly effective and efficient management of energy, and they have the potential to increase sustainability. The applicability of such super grids in the sub-Saharan African context is still uncertain and is scientifically under-explored; thus there is

Abstract. It is the purpose of this paper to document the NCAR global model topography generation software for unstructured grids (NCAR_Topo (v1.0)). Given a model grid, the software computes the fraction of the grid box covered by land, the grid-box mean elevation (deviation from a geoid that defines nominal sea level surface), and associated sub-grid-scale variances commonly used for gravity wave and turbulent mountain stress parameterizations. The software supports regular latitude–longitude grids as well as unstructured grids, e.g., icosahedral, Voronoi, cubed-sphere and variable-resolutio

Abstract. Mountain regions are highly sensitive to global climate change. However, large scale assessments of mountain environments remain problematic due to the high resolution required of model grids to capture strong lateral variability. To alleviate this, tools are required to bridge the scale gap between gridded climate datasets (climate models and re-analyses) and unresolved (by coarse grids) sub-grid mountain topography. We address this problem with a sub-grid method. It relies on sampling the most important aspects of land surface heterogeneity through a lumped scheme, allowing for the

Such methods are extremely effective for the interior part of the flow, but they suffer from the disadvantage that they do not represent solid surfaces as accurately as body fitted grids. This difficulty can in part be overcome by using a polygonal representation of the body surface (Leveque 1988, Quirk 1992), but it is then impossible to avoid the presence of extremely small cells which lead to v
