RISThe Stability and Genesis of Rossby Vortices
Publisher: American Meteorological Society
Abstract: The stability and genesis of the vortices associated with long solitary divergent Rossby waves-the Rossby vortices?are studied numerically using the single-layer (SL) model with Jovian parameters. Vortex behavior depends ...
A Very High Resolution General Circulation Model Simulation of the Global Circulation in Austral Winter
Publisher: American Meteorological Society
Abstract: This paper discusses a simulation obtained with the Geophysical Fluid Dynamics Laboratory ?SKYHI? troposphere?stratosphere?mesosphere general circulation model run at very high horizontal resolution (?60-km grid spacing) ...
Middle Atmosphere Simulated with High Vertical and Horizontal Resolution Versions of a GCM: Improvements in the Cold Pole Bias and Generation of a QBO-like Oscillation in the Tropics
Publisher: American Meteorological Society
Abstract: The large-scale circulation in the Geophysical Fluid Dynamics Laboratory ?SKYHI? troposphere?stratosphere?mesosphere finite-difference general circulation model is examined as a function of vertical and horizontal resolution. ...
An Analysis of the Effect of Topography on the Martian Hadley Cells
Publisher: American Meteorological Society
Abstract: Previous work with Mars general circulation models (MGCMs) has shown that the north?south slope in Martian topography causes asymmetries in the Hadley cells at equinox and in the annual average. To quantitatively solve for ...
Spontaneous Stratospheric QBO-like Oscillations Simulated by the GFDL SKYHI General Circulation Model
Publisher: American Meteorological Society
Abstract: The tropical stratospheric mean flow behavior in a series of integrations with high vertical resolution versions of the Geophysical Fluid Dynamics Laboratory (GFDL) ?SKYHI? model is examined. At sufficiently high vertical ...
Local Dynamics of Baroclinic Waves in the Martian Atmosphere
Publisher: American Meteorological Society
Abstract: he paper investigates the processes that drive the spatiotemporal evolution of baroclinic transient waves in the Martian atmosphere by a simulation experiment with the Geophysical Fluid Dynamics Laboratory (GFDL) Mars ...
Stratospheric Ozone and Temperature Simulated from the Preindustrial Era to the Present Day
Publisher: American Meteorological Society
Abstract: esults from the simulation of a coupled chemistry?climate model are presented for the period 1860 to 2005 using the observed greenhouse gas (GHG) and halocarbon concentrations. The model is coupled to a simulated ocean and ...
Effects of the Mean Flow on Martian Transient Eddy Activity: Studies with an Idealized General Circulation Model
Publisher: American Meteorological Society
Abstract: AbstractThe extent to which the eddy statistics of the Martian atmosphere can be inferred from the mean state and highly simplified assumptions about diabatic and frictional processes is investigated using an idealized ...
The Dynamical Core, Physical Parameterizations, and Basic Simulation Characteristics of the Atmospheric Component AM3 of the GFDL Global Coupled Model CM3
Publisher: American Meteorological Society
Abstract: he Geophysical Fluid Dynamics Laboratory (GFDL) has developed a coupled general circulation model (CM3) for the atmosphere, oceans, land, and sea ice. The goal of CM3 is to address emerging issues in climate change, including ...
