RISA Weather-Type Approach to Analyzing Winter Precipitation in France: Twentieth-Century Trends and the Role of Anthropogenic Forcing
Publisher: American Meteorological Society
Abstract: The relationship between large-scale atmospheric circulation and November?March precipitation over France during the twentieth century is investigated. A long daily MSLP dataset is used to derive daily weather types that ...
Tropical Atlantic Sea Surface Temperature Forcing of Quasi-Decadal Climate Variability over the North Atlantic–European Region
Publisher: American Meteorological Society
Abstract: Effects of Atlantic sea surface temperature (SST) anomalies on the North Atlantic low-frequency atmospheric variability are examined by analyzing two ensembles of integrations of the ARPEGE general circulation model (GCM) ...
Distributed Ocean–Atmosphere Modeling and Sensitivity to the Coupling Flux Precision: The CATHODe Project
Publisher: American Meteorological Society
Abstract: The authors present the distribution of a coupled ocean?atmosphere global circulation model. The atmospheric (ARPEGE) and the oceanic (OPA) components run separately at different sites; the coupling is achieved through the ...
Representing El Niño in Coupled Ocean–Atmosphere GCMs: The Dominant Role of the Atmospheric Component
Publisher: American Meteorological Society
Abstract: A systematic modular approach to investigate the respective roles of the ocean and atmosphere in setting El Niño characteristics in coupled general circulation models is presented. Several state-of-the-art coupled models ...
Interannual to Decadal Climate Predictability in the North Atlantic: A Multimodel-Ensemble Study
Publisher: American Meteorological Society
Abstract: Ensemble experiments are performed with five coupled atmosphere?ocean models to investigate the potential for initial-value climate forecasts on interannual to decadal time scales. Experiments are started from similar ...
The Seasonal Cycle over the Tropical Pacific in Coupled Ocean–Atmosphere General Circulation Models
Publisher: American Meteorological Society
Abstract: The seasonal cycle over the tropical Pacific simulated by 11 coupled ocean?atmosphere general circulation models (GCMs) is examined. Each model consists of a high-resolution ocean GCM of either the tropical Pacific or ...
