Cloud Feedback Processes in a General Circulation Model
Publisher: American Meteorological Society
Abstract: The influence of the cloud feedback process upon the sensitivity of climate is investigated by comparing the behavior of two versions of a climate model with predicted and prescribed cloud cover. The model used for this ...
Large-Scale Changes of Soil Wetness Induced by an Increase in Atmospheric Carbon Dioxide
Publisher: American Meteorological Society
Abstract: The change in soil wetness in response to an increase of atmospheric concentration of carbon dioxide is investigated by two versions of a climate model which consists of a general circulation model of the atmosphere and a ...
The Effects of Orography on Midlatitude Northern Hemisphere Dry Climates
Publisher: American Meteorological Society
Abstract: The role of mountains in maintaining extensive midlatitude arid regions in the Northern Hemisphere was investigated using simulations from the GFDL Global Climate Model with and without orography. In the integration with ...
AN INVESTIGATION OF THERMAL TIDAL OSCILLATIONS IN THE EARTH'S ATMOSPHERE USING A GENERAL CIRCULATION MODEL
Publisher: American Meteorological Society
Abstract: An investigation of tidal oscillations in the earth's atmosphere has been made using an 18 vertical level, hemispheric general circulation model. This approach permitted these tides to be investigated without resorting to ...
The Mechanisms of Summer Dryness Induced by Greenhouse Warming
Publisher: American Meteorological Society
Abstract: To improve understanding of the mechanisms responsible for CO2-induced, midcontinental summer dryness obtained by earlier modeling studies, several integrations were performed using a GCM with idealized geography. The ...
A Comparison of Climate Model Sensitivity with Data from the Last Glacial Maximum
Publisher: American Meteorological Society
Abstract: An attempt has been made to use paleoclimatic data from the last glacial maximum to evaluate the sensitivity of two versions of an atmosphere/mixed-layer ocean model. Each of these models has been used to study the C02-induced ...
Two Stable Equilibria of a Coupled Ocean-Atmosphere Model
Publisher: American Meteorological Society
Abstract: Two stable equilibria have been obtained from a global model of the coupled ocean-atmosphere system developed at the Geophysical Fluid Dynamics Laboratory of NOAA. The model used for this study consists of general circulation ...
Interhemispheric Asymmetry in the Transient Response of a Coupled Ocean–Atmosphere Model to a CO2 Forcing
Publisher: American Meteorological Society
Abstract: Numerical experiments are carried out using a general circulation model of a coupled ocean-atmosphere system with idealized geography, exploring the transient response of climate to a rapid increase of atmospheric carbon ...
Interdecadal Variations of the Thermohaline Circulation in a Coupled Ocean-Atmosphere Model
Publisher: American Meteorological Society
Abstract: A fully coupled ocean-atmosphere model is shown to have irregular oscillations of the thermohaline circulation in the North Atlantic Ocean with a time scale of approximately 50 years. The irregular oscillation appears to ...
