The Role of Variable Coriolis Parameter in the Propagation of Inertia-Gravity Waves During the Process of Geostrophic Adjustment
Publisher: American Meteorological Society
Abstract: This analysis treats the transient inertia-gravity wave response of a shallow fluid to an impulsive addition of momentum. The Coriolis parameter varies with latitude, but Rossby waves are not considered. The square of the ...
VERTICAL MOTION FIELD IN THE MIDDLE THERMOSPHERE FROM SATELLITE DRAG DENSITIES
Publisher: American Meteorological Society
Abstract: The vertical motion field in the thermosphere is calculated from the continuity equation. This calculation is based on a field of horizontal winds and an intermediate model of the thermospheric temperature field consistent ...
Numerical Study of an Interacting Rossby Wave and Barotropic Zonal Flow Near a Critical Level
Publisher: American Meteorological Society
Abstract: This paper treats the initial value problem of a forced Rossby wave encountering a critical level in a barotropic zonal shear flow which can change in response to the wave momentum flux divergence. The main result of the ...
The Project for Intercomparison of Land-surface Parameterization Schemes
Publisher: American Meteorological Society
Abstract: The Project for Intercomparison of Land-surface Parameterization Schemes (PILPS) is described and the first stage science plan outlined. PILPS is a project designed to improve the parameterization of the continental surface, ...
A Comparison of CCM2–BATS Skin Temperature and Surface-Air Temperature with Satellite and Surface Observations
Publisher: American Meteorological Society
Abstract: This paper reports on two types of comparisons that were conducted. First, 10-yr modeled skin temperatures were compared with observations to evaluate model simulations of this quantity. The simulations were conducted with ...
Further FGGE Forecasts for Amazon Basin Rainfall
Publisher: American Meteorological Society
Abstract: A series of experiments using real-data general circulation model integrations is performed to study the impact of remote tropical Pacific heating modifications upon the rainfall over the Amazon Basin. In one set of ...
Sensitivity of the Biosphere–Atmosphere Transfer Scheme (BATS) to the Inclusion of Variable Soil Characteristics
Publisher: American Meteorological Society
Abstract: The soils data of Wilson and Henderson-Sellers have been incorporated into the land-surface parameterization scheme of the NCAR Community Climate Model after Dickinson. A stand-alone version of this land-surface scheme, ...
Using MODIS BRDF and Albedo Data to Evaluate Global Model Land Surface Albedo
Publisher: American Meteorological Society
Abstract: The land surface albedo in the NCAR Community Climate System Model (CCSM2) is calculated based on a two-stream approximation, which does not include the effect of three-dimensional vegetation structure on radiative transfer. ...
