Meridional Ocean Carbon Transport

NOTES AND CORRESPONDENCE Global Ocean Meridional Overturning

A decade-mean global ocean circulation is estimated using inverse techniques, incorporating air–sea fluxes of heat and freshwater, recent hydrographic sections, and direct current measurements. This information is used to determine mass, heat, freshwater, and other chemical transports, and to constrain boundary currents and dense overflows. The 18 boxes defined by these sections are divided int...

Mechanisms Maintaining Southern Ocean Meridional Heat Transport under Projected Wind Forcing

Meridional heat transport (MHT) in the Southern Ocean (SO) and its components are analyzed with two eddy-permitting climate models. The two models present a consistent picture of the MHT response to projected twenty-first-century changes in SO winds. In agreement with a recent analysis based on an ocean data synthesis product, much of the MHT in the SO is found to be due to the time-mean fields...

Meridional Energy Transport: Uncertainty in Zonal Means

The meridional energy transport in the atmosphere and ocean is computed using atmospheric analyses from ECMWF and NMC, and net radiative ux from ERBE. An error analysis of the zonally-averaged total transport shows that errors of 7 Wm 2 in net ux produce transport errors of 0:5PW at the equator, an error of 9% in midlatitudes. Methods for correcting the mass non-conservation in transports deriv...

Meridional Transport in the Stratosphere of Jupiter

The Cassini measurements of C2H2 and C2H6 at ∼5 mbar provide a constraint on meridional transport in the stratosphere of Jupiter. We performed a two-dimensional photochemical calculation coupled with mass transport due to vertical and meridional mixing. The modeled profile of C2H2 at latitudes less than 70 follows the latitude dependence of the solar insolation, while that of C2H6 shows little ...
