RISA New Fourth-Order Enstrophy and Energy Conserving Scheme
Publisher: American Meteorological Society
Abstract: A new pseudo-fourth-order finite-difference scheme for the shallow-water and primitive equations is derived. This scheme is a C-grid scheme that conserves energy and conserves enstrophy in the nondivergent limit. The ...
Generalized Energy and Potential Enstrophy Conserving Finite Difference Schemes for the Shallow Water Equations
Publisher: American Meteorological Society
Abstract: The conditions under which finite difference schemes for the shallow water equations can conserve both total energy and potential enstrophy are considered. A method of deriving such schemes using operator formalism is ...
Land-Surface Model Development for the GISS GCM
Publisher: American Meteorological Society
Abstract: A land-surface model is linked to the Goddard Institute for Space Studies (GISS) GCM Model II to form Model II-LS. The land-surface model primarily influences the simulation of surface air temperature over land, both in ...
Using Similarity Theory to Parameterize Mesoscale Heat Fluxes Generated by Subgrid-Scale Landscape Discontinuities in GCMs
Publisher: American Meteorological Society
Abstract: Similarity theory was used to develop a parameterization of mesoscale heat fluxes induced by landscape discontinuities for large-scale atmospheric models (e.g., general circulation models). For this purpose, Buckingham Pi ...
A Parameterization for the Triggering of Landscape-Generated Moist Convection. Part I: Analysis of High-Resolution Model Results
Publisher: American Meteorological Society
Abstract: To develop a parameterization for the triggering of moist convection by landscape-generated mesoscale circulations, a set of relatively high-resolution three-dimensional (3D) simulations was produced. These simulations ...
