Oceanic Regulation of the Atmospheric Walker Circulation
A coupled theory is proposed to account for the magnitude of the Walker circulation in the tropical Pacific. It is suggested that the Pacific Walker circulation is at a saturation state, at which the zonal sea surface temperature difference is bounded by about a quarter of the latitudinal difference of the radiative–convective equilibrium sea surface temperature.

متن کاملIrreducible imprecision in atmospheric and oceanic simulations.
Atmospheric and oceanic computational simulation models often successfully depict chaotic space-time patterns, flow phenomena, dynamical balances, and equilibrium distributions that mimic nature. This success is accomplished through necessary but non-unique choices for discrete algorithms, parameterizations, and coupled contributing processes that introduce structural instability into the model...
متن کاملModes of Oceanic and Atmospheric Circulation During the Quaternary
Paleoclimatic evidence shows that the ocean and atmosphere have undergone major changes during the Quaternary. For atmospheric mean circulation, data are consistent with changes in strength and shifts in position of major atmospheric circulation features (e.g., the westerly wind belt), whereas the structure of these main features appears to have persisted. For the ocean, evidence points to qual...
متن کاملAtmospheric and oceanic freshwater transport during weak Atlantic overturning circulation
Oceanic and atmospheric freshwater transports are analyzed in a numerical experiment where induced freshwater in the North Atlantic slowed the thermohaline circulation (THC). During times of weak Atlantic overturning circulation, it is found that the Intertropical Convergence Zone moves southward and trade winds at tropical latitudes increase, resulting in enhanced water vapor export out of the...
متن کاملImpact of oceanic circulation changes on atmospheric 13CO2
δCO2 measured in Antarctic ice cores provides constraints on oceanic and terrestrial carbon cycle processes linked with millennial-scale changes in atmospheric CO2. However, the interpretation of δCO2 is not straightforward. Using carbon isotope-enabled versions of the LOVECLIM and Bern3D models, we perform a set of sensitivity experiments in which the formation rates of North Atlantic Deep Wat...
