Energy Transfers for Multilayer Hydrodynamic Ocean Models: General Formulation and Specific Examples
Abstract
Two dynamic models, useful in studying ocean circulations, are treated: the inviscid multilayer hydrodynamic model and the inviscid multilayer reduced-gravy hydrodynamic model or, for brevity, the finite depth model and the reduced-gravity model. The two models are identical except that the velocity is required to be zero in the bottom layer of the reduced-gravity model. The latter model retains most of the physical properties of the finite depth model but has considerably fewer computational requirements. Two different formulations of the energetics are obtained: layer-layer and layer-interface. In both, the kinetic energy per unit area of a layer is specified. Both formulations are valid mathematically and physically so the selection of one depends on what types of energy transfers the user wishes to examine. The energetics, or energy analysis, is presented for a general multilayer case for both models and both formulations. The energetics in both formulations are considered for specific cases: the one-, two-, and three-layer cases for the finite depth model and the one and two active layer cases for the reduced-gravity model.
