RISNorth Atlantic Interannual Variability in a Coupled Ocean–Atmosphere Model
Publisher: American Meteorological Society
Abstract: The primary mode of sea surface temperature variability in the North Atlantic on interannual timescales during winter is examined in a coupled ocean?atmosphere model. The model, developed at die Geophysical Fluid Dynamics ...
The Influence of Soil Wetness on Near-Surface Atmospheric Variability
Publisher: American Meteorological Society
Abstract: The influence of land surface processes on near-surface atmospheric variability on seasonal and interannual time scales is studied using output from two integrations of a general circulation model. In the first experiment ...
The Influence of Potential Evaporation on the Variabilities of Simulated Soil Wetness and Climate
Publisher: American Meteorological Society
Abstract: An atmospheric general circulation model with prescribed sea surface temperature and cloudiness was integrated for 50 years in order to study atmosphere-land surface interactions. The temporal variability of model soil ...
Decadal Variability of the Tropical Atlantic Ocean Surface Temperature in Shipboard Measurements and in a Global Ocean-Atmosphere Model
Publisher: American Meteorological Society
Abstract: Numerous analyses of relatively short (25?30 years in length) time series of the observed surface temperature of the tropical Atlantic Ocean have indicated the possible existence of decadal timescale variability. It was ...
Simulated Tropical Response to a Substantial Weakening of the Atlantic Thermohaline Circulation
Publisher: American Meteorological Society
Abstract: In this study, a mechanism is demonstrated whereby a large reduction in the Atlantic thermohaline circulation (THC) can induce global-scale changes in the Tropics that are consistent with paleoevidence of the global ...
The Role of Mesoscale Eddies in the Remote Oceanic Response to Altered Southern Hemisphere Winds
Publisher: American Meteorological Society
Abstract: It has been suggested that a strengthening of the Southern Hemisphere winds would induce a more vigorous overturning through an increased northward Ekman flux, bringing more light waters into the oceanic basins and enhancing ...
Analysis of the Characteristics and Mechanisms of the Pacific Decadal Oscillation in a Suite of Coupled Models from the Geophysical Fluid Dynamics Laboratory
Publisher: American Meteorological Society
Abstract: orth Pacific decadal oceanic and atmospheric variability is examined in a suite of coupled climate models developed at the Geophysical Fluid Dynamics Laboratory (GFDL). The models have ocean horizontal resolutions ranging ...
The Impact of the North Atlantic Oscillation on Climate through Its Influence on the Atlantic Meridional Overturning Circulation
Publisher: American Meteorological Society
Abstract: he impact of the North Atlantic Oscillation (NAO) on the Atlantic meridional overturning circulation (AMOC) and large-scale climate is assessed using simulations with three different climate models. Perturbation experiments ...
Detectability of Decadal Anthropogenic Hydroclimate Changes over North America
Publisher: American Meteorological Society
Abstract: AbstractRegional hydroclimate changes on decadal time scales contain substantial natural variability. This presents a challenge for the detection of anthropogenically forced hydroclimate changes on these spatiotemporal ...

Publisher: American Meteorological Society
Abstract: AbstractThe average predictability time (APT) method is used to identify the most predictable components of decadal sea surface temperature (SST) variations over the Southern Ocean (SO) in a 4000-yr unforced control run ...
