Why Anticyclones Can Split
Publisher: American Meteorological Society
Abstract: The question of whether anticyclones can split and break up is readdressed using a numerical, multilayer, primitive equation model. Applying the conservation of integrated angular momentum (IAM) to barotropic and baroclinic ...

What Sets the Surface Eddy Mass Flux in the Southern Ocean?
Publisher: American Meteorological Society
Abstract: The Ocean Circulation and Climate Advanced Modelling (OCCAM) global, eddy-permitting ocean general circulation model has been used to investigate the surface eddy mass flux in the Southern Ocean. The isopycnal eddy mass ...
Ring Genesis and the Related Transports of Heat, Momentum and Vorticity: A Parameter Study
Publisher: American Meteorological Society
Abstract: The transport of heat, momentum and vorticity during the fife cycle of an unstable baroclinic wave that displays ring formation are investigated. Experiments have been carried out with a primitive equation numerical model. ...
Stochastically Forced Mode Water Variability
Publisher: American Meteorological Society
Abstract: Substantial interannual to decadal variability is observed in the properties of subtropical mode water of the North Atlantic. In this study the response of mode water to stochastic atmospheric forcing is investigated in a ...
Eddy Subduction in a Model of the Subtropical Gyre
Publisher: American Meteorological Society
Abstract: Subduction is the process by which fluid transfers from the mixed layer to the interior of the ocean. South of the Gulf Stream extension, 18° mode water is formed in a region of high subduction rates. In this region there ...
The Lagrangian View of South Atlantic Interocean Exchange in a Global Ocean Model Compared with Inverse Model Results
Publisher: American Meteorological Society
Abstract: Data from a global ocean general circulation model (OCCAM) has been used to investigate the interocean exchange of thermocline and intermediate waters in the South Atlantic Ocean. To resolve the pathways between different ...
Detecting Atlantic MOC Changes in an Ensemble of Climate Change Simulations
Publisher: American Meteorological Society
Abstract: Signal-to-noise patterns for the meridional overturning circulation (MOC) have been calculated for an ensemble of greenhouse scenario runs. The greenhouse-forced signal has been defined as the linear trend in ensemble-mean ...
Mode Water Variability in a Model of the Subtropical Gyre: Response to Anomalous Forcing
Publisher: American Meteorological Society
Abstract: The response of mode water formation to typical atmospheric forcing anomalies is studied as a possible mechanism for generating the observed interannual to decadal variability in mode water. An isopycnal model of the North ...
Water Mass Transformation and Subduction in the South Atlantic
Publisher: American Meteorological Society
Abstract: The transformation of water masses induced by air?sea fluxes in the South Atlantic Ocean is calculated with a global ocean model, Ocean Circulation and Climate Advanced Modeling (OCCAM), and has been compared with several ...
