RISPredictions of Indian Ocean SST Indices with a Simple Statistical Model: A Null Hypothesis
Publisher: American Meteorological Society
Abstract: Several recent general circulation model studies discuss the predictability of the Indian Ocean dipole (IOD) mode, suggesting that it is predictable because of coupled ocean?atmosphere interactions in the Indian Ocean. ...
Macroturbulent Equilibration in a Thermally Forced Primitive Equation System
Publisher: American Meteorological Society
Abstract: major question for climate studies is to quantify the role of turbulent eddy fluxes in maintaining the observed ocean?atmosphere state. It has been argued that eddy fluxes keep the midlatitude atmosphere in a state that ...
The Turbulent Circulation of a Snowball Earth Ocean
Publisher: American Meteorological Society
Abstract: heoretical arguments are developed to derive general properties of the ocean circulation in a ?snowball? world, and the predictions are confirmed in a series of idealized numerical simulations. As suggested previously, a ...
Equilibration of an Atmosphere by Adiabatic Eddy Fluxes
Publisher: American Meteorological Society
Abstract: major question for climate studies is to quantify the role of turbulent eddy fluxes in maintaining the observed atmospheric mean state. Both the equator-to-pole temperature gradient and the static stability of the extratropical ...
The Vertical Structure of the Eddy Diffusivity and the Equilibration of the Extratropical Atmosphere
Publisher: American Meteorological Society
Abstract: bservations suggest that the time- and zonal-mean state of the extratropical atmosphere adjusts itself such that the so-called ?criticality parameter? (which relates the vertical stratification to the horizontal temperature ...
The Impact of Topography and Eddy Parameterization on the Simulated Southern Ocean Circulation Response to Changes in Surface Wind Stress
Publisher: American Meteorological Society
Tropical Atmosphere–Ocean Interactions in a Conceptual Framework
Publisher: American Meteorological Society
Abstract: Statistical analysis of observations (including atmospheric reanalysis and forced ocean model simulations) is used to address two questions: First, does an analogous mechanism to that of El Niño?Southern Oscillation (ENSO) ...
Equilibration of a Baroclinic Planetary Atmosphere toward the Limit of Vanishing Bottom Friction
Publisher: American Meteorological Society
Abstract: his paper discusses whether and how a baroclinic atmosphere can equilibrate with very small bottom friction in a dry primitive equation general circulation model. The model is forced by a Newtonian relaxation of temperature ...
Eddy Phase Speeds in a Two-Layer Model of Quasigeostrophic Baroclinic Turbulence with Applications to Ocean Observations
Publisher: American Meteorological Society
Abstract: he phase speed spectrum of ocean mesoscale eddies is fundamental to understanding turbulent baroclinic flows. Since eddy phase propagation has been shown to modulate eddy fluxes, an understanding of eddy phase speeds is ...
The Effect of Southern Ocean Surface Buoyancy Loss on the Deep-Ocean Circulation and Stratification
Publisher: American Meteorological Society
Abstract: he deep-ocean circulation and stratification have likely undergone major changes during past climates, which may have played an important role in the modulation of atmospheric CO2 concentrations. The mechanisms by which ...
