Internal Wave Breaking at Concave and Convex Continental Slopes
Publisher: American Meteorological Society
Abstract: Internal wave reflection from a sloping topographic boundary may lead to enhanced shear if the topographic angle to the horizontal is close to that of the internal wave group velocity vector. Previous analytic studies have ...
Representation of Topography by Shaved Cells in a Height Coordinate Ocean Model
Publisher: American Meteorological Society
Abstract: Height coordinate ocean models commonly represent topography as a ?staircase? of discontinuous steps that are fitted to the model grid. Here the ramifications of an alternative approach are studied in which ?shaved cells? ...
How Sensitive Are Coarse General Circulation Models to Fundamental Approximations in the Equations of Motion?
Publisher: American Meteorological Society
Abstract: The advent of high-precision gravity missions presents the opportunity to accurately measure variations in the distribution of mass in the ocean. Such a data source will prove valuable in state estimation and constraining ...
Implementation of an Atmosphere–Ocean General Circulation Model on the Expanded Spherical Cube
Publisher: American Meteorological Society
Abstract: A hydrodynamical kernel that drives both an atmospheric and oceanic general circulation model is implemented in general orthogonal curvilinear coordinates using the finite-volume method on the sphere. The finite-volume ...
Energy Flux into Internal Lee Waves: Sensitivity to Future Climate Changes Using Linear Theory and a Climate Model
Publisher: American Meteorological Society
Abstract: nternal lee waves generated by geostrophic flows over rough topography are thought to be a significant energy sink for eddies and energy source for deep ocean mixing. The sensitivity of the energy flux into lee waves from ...
Atmosphere–Ocean Modeling Exploiting Fluid Isomorphisms
Publisher: American Meteorological Society
Abstract: Mathematical isomorphisms between the hydrostatic equations that govern the evolution of a compressible atmosphere and an incompressible ocean are described and exploited to guide the design of a hydrodynamical kernel for ...
Influence of Ocean and Atmosphere Components on Simulated Climate Sensitivities
Publisher: American Meteorological Society
Abstract: he influence of alternative ocean and atmosphere subcomponents on climate model simulation of transient sensitivities is examined by comparing three GFDL climate models used for phase 5 of the Coupled Model Intercomparison ...
Sensitivity of Twenty-First-Century Global-Mean Steric Sea Level Rise to Ocean Model Formulation
Publisher: American Meteorological Society
Abstract: wo comprehensive Earth system models (ESMs), identical apart from their oceanic components, are used to estimate the uncertainty in projections of twenty-first-century sea level rise due to representational choices in ocean ...
Simulated Climate and Climate Change in the GFDL CM2.5 High-Resolution Coupled Climate Model
Publisher: American Meteorological Society
Abstract: he authors present results for simulated climate and climate change from a newly developed high-resolution global climate model [Geophysical Fluid Dynamics Laboratory Climate Model version 2.5 (GFDL CM2.5)]. The GFDL CM2.5 ...
GFDL’s ESM2 Global Coupled Climate–Carbon Earth System Models. Part II: Carbon System Formulation and Baseline Simulation Characteristics
Publisher: American Meteorological Society
Abstract: he authors describe carbon system formulation and simulation characteristics of two new global coupled carbon?climate Earth System Models (ESM), ESM2M and ESM2G. These models demonstrate good climate fidelity as described ...
