RISOcean Dynamics, Thermocline Adjustment, and Regulation of Tropical SST
Publisher: American Meteorological Society
Abstract: The role of tropical Pacific ocean dynamics in regulating the ocean response to thermodynamic forcing is investigated using an ocean general circulation model (GCM) coupled to a model of the atmospheric mixed layer. It is ...
Interannual Variability of the Dynamics and Thermodynamics of the Tropical Indian Ocean
Publisher: American Meteorological Society
Abstract: Interannual variability of the tropical Indian Ocean is studied with a reduced gravity, primitive equation, ocean general circulation model (OGCM). The OGCM is coupled to an atmospheric mixed layer model for surface heat ...
A Reduced-Gravity, Primitive Equation, Isopycnal Ocean GCM: Formulation and Simulations
Publisher: American Meteorological Society
Abstract: A reduced gravity, primitive equation, ocean GCM with an isopycnal vertical coordinate is developed. A ?buffer? layer is introduced to allow the mixed layer to detrain mass at arbitrary densities without the coordinate ...
Simulation of the Tropical Oceans with an Ocean GCM Coupled to an Atmospheric Mixed-Layer Model
Publisher: American Meteorological Society
Abstract: A reduced gravity, primitive equation, ocean general circulation model (GCM) is coupled to an advective atmospheric mixed-layer (AML) model to demonstrate the importance of a nonlocal atmospheric mixed-layer parameterization ...
Quantification of the Feedback between Phytoplankton and ENSO in the Community Climate System Model
Publisher: American Meteorological Society
Abstract: The current coarse-resolution version of the Community Climate System Model is used to assess the impact of phytoplankton on El Niño?Southern Oscillation (ENSO). The experimental setup allows for the separation of the ...
Why is There an Evaporation Minimum at the Equator?
Publisher: American Meteorological Society
Abstract: At all longitudes oceanic evaporation rates are lower on the equator than at latitudes to the north and south. Over the oceanic cold tongues this is related to the presence of cold water and divergence of heat by the ocean ...
Application of a Reduced-Order Kalman Filter to Initialize a Coupled Atmosphere–Ocean Model: Impact on the Prediction of El Niño
Publisher: American Meteorological Society
Abstract: A reduced-order Kalman filter is used to assimilate observed fields of the surface wind stress, sea surface temperature, and sea level into the coupled ocean?atmosphere model of Zebiak and Cane. The method projects the ...
Biophysical Feedbacks in the Tropical Pacific
Publisher: American Meteorological Society
Abstract: This study explores the influence of phytoplankton on the tropical Pacific heat budget. A hybrid coupled model for the tropical Pacific that is based on a primitive equation reduced-gravity multilayer ocean model, a dynamic ...
Air–Sea Interaction and the Seasonal Cycle of the Subtropical Anticyclones
Publisher: American Meteorological Society
Abstract: The causes of the seasonal cycles of the subtropical anticyclones, and the associated zonal asymmetries of sea surface temperature (SST) across the subtropical oceans, are examined. In all basins the cool waters in the ...
