The Effects of Inertia on the General Circulation in an Ocean with Bottom Topography

OCE96-33057贝克尔项目将使用两种类型的大气环流模式来研究地形和层结对西部边界流的影响，这是准地转模式所不能解决的。第一个模型由原始方程控制，但约束为正压模型。通过“大陆架”平稳过渡到零深度的侧壁的有限差分解将与垂直侧壁的标准情况进行比较。第二种模式也将包括倾斜的侧壁，但将是分层的。垂直模式将被用来避免层界面与边界相交时的数值困难。这些结果将有助于阐明数值大气环流模式中控制风生流动的动力过程。

OCE 96-33057 Becker The project will use two types of general circulation models to investigate effects of topography and stratification on western boundary currents which cannot be addressed by quasi-gestrophic models. The first model is governed by primitive equations, but constrained to be barotropic. Finite difference solutions for the case of sidewalls which transition smoothly to zero depth through a "continental shelf" will be compared to the standard case of vertical sidewalls. The second model will also incorporate sloping sidewalls, but will be stratified. Vertical modes will be used to avoid numerical difficulties where layer interfaces intersect the boundaries. The results will clarify dynamical processes controlling wind driven flow in numerical general circulation models.
