The Global Zonally Integrated Ocean Circulation, 1992–2006: Seasonal and Decadal Variability

The Global Zonally Integrated Ocean Circulation, 1992–2006: Seasonal and Decadal Variability

The zonally integrated meridional and vertical velocities as well as the enthalpy transports and fluxes in a least squares adjusted general circulation model are used to estimate the top-to-bottom oceanic meridional overturning circulation (MOC) and its variability from 1992 to 2006. A variety of simple theories all produce time scales suggesting that the midand high-latitude oceans should resp...

15 Decadal Variability of the Thermohaline Ocean Circulation

The decadal mean ocean circulation and Sverdrup balance

Elementary Sverdrup balance is tested in the context of the time-average of a 16-year duration time-varying ocean circulation estimate employing the great majority of globalscale data available between 1992 and 2007. The time-average circulation exhibits all of the conventional major features as depicted both through its absolute surface topography and vertically integrated transport stream fun...

Decadal variability of the North Atlantic in an ocean general circulation model

Climatic fluctuations on a decadal timescale in the North Atlantic in a global ocean general circulation model were considered. The analysis was carried out for the 3800-year stochastic forcing simulation of Mikolajewicz and Maier-Reimer in which the Hamburg LargeScale Geostrophic ocean model was driven by monthly climatologies of wind stress, air temperature, and freshwater flux with superimpo...

Decadal changes in global ocean chlorophyll

[1] The global ocean chlorophyll archive produced by the CZCS was revised using compatible algorithms with SeaWiFS. Both archives were then blended with in situ data to reduce residual errors. This methodology permitted a quantitative comparison of decadal changes in global ocean chlorophyll from the CZCS (1979–1986) and SeaWiFS (1997–2000) records. Global spatial distributions and seasonal var...
