Publisher: American Meteorological Society
A Stable Centered Difference Scheme Free of Two-Grid-Interval Noise
Publisher: American Meteorological Society
Abstract: A procedure leading to a stable space-centered, leapfrog time-differencing scheme, capable of preventing the false two-grid-interval noise that arises when two large-scale solutions are separated an different elementary ...
On the Pressure Gradient Force Error in σ-Coordinate Spectral Models
Publisher: American Meteorological Society
Abstract: The pressure gradient force error of the spectral technique used in combination with the σ vertical coordinate was examined in an idealized case of an atmosphere at rest and in hydrostatic equilibrium. Small-scale (one-point ...
The Step-Mountain Coordinate: Physical Package
Publisher: American Meteorological Society
Abstract: A comprehensive physical package has been developed for a regional eta coordinate model with the steplike mountain representation. This paper describes the basic problems, concepts and numerical techniques developed, and ...
Nonlinear Advection Schemes and Energy Cascade on Semi-Staggered Grids
Publisher: American Meteorological Society
Abstract: A common problem with nonlinear advection schemes is the false accumulation of energy at the smallest resolvable scales. To keep this process under control, following Arakawa (1966), a number of energy and enstrophy ...
The Step-Mountain Eta Coordinate Model: Further Developments of the Convection, Viscous Sublayer, and Turbulence Closure Schemes
Publisher: American Meteorological Society
Abstract: The step-mountain eta model has shown a surprising skill in forecasting severe storms. Much of the credit for this should be given to the Betts and Miller (hereafter referred to as BM) convection scheme and the Mellor-Yamada ...
Topographically Induced Stationary Solutions of Linearized Shallow Water Equations on Various Grids
Publisher: American Meteorological Society
Abstract: The effect of the grid choice on the stationary solutions of the linearized shallow water equations in the presence of topography is examined. The time-averaged numerical solutions on the C grid reported by Arakawa and ...
Verification of the New Nonhydrostatic Multiscale Model on the B Grid (NMMB): A View on Global Predictability of Surface Parameters
Publisher: American Meteorological Society
Abstract: global verification of temperature, dewpoint temperature, and wind speed for the new Nonhydrostatic Multiscale Model on the B Grid (NMMB) is computed for a 3-yr period (2010?12) using over 9000 weather stations. The raw ...
A Class of Conservative Fourth-Order Advection Schemes and Impact of Enhanced Formal Accuracy on Extended-Range Forecasts
Publisher: American Meteorological Society
Abstract: tarting from three Eulerian second-order nonlinear advection schemes for semi-staggered Arakawa grids B/E, advection schemes of fourth order of formal accuracy were developed. All three second-order advection schemes control ...
Assessment of the Land Surface and Boundary Layer Models in Two Operational Versions of the NCEP Eta Model Using FIFE Data
Publisher: American Meteorological Society
Abstract: Data from the 1987 summer FIFE experiment for four pairs of days are compared with corresponding 48-h forecasts from two different versions of the Eta Model, both initialized from the NCEP?NCAR (National Centers for ...
