2012 JOURNAL OF PHYSICAL OCEANOGRAPHY VOLUME 36 Estimated Decadal Changes in the North Atlantic Meridional Overturning Circulation and Heat Flux 1993–2004
Results from a global 1 ° model constrained by least squares to a multiplicity of datasets over the interval 1992–2004 are used to describe apparent changes in the North Atlantic Ocean meridional overturning circulation and associated heat fluxes at 26°N. The least squares fit is both stable and ade...
