  abstract = {{P}revious studies have linked the slowdown in global surface temperature warming during the 1998-2012 period to a negative {I}nterdecadal {P}acific {O}scillation ({IPO}) phase. {H}ere, we investigate the changes in ocean heat content ({OHC}) during this period. {W}e compare two ensembles of coupled model experiments with either zero or observed prescribed tropical {P}acific wind stress interannual anomalies. {T}his successfully constrains the global surface temperature, sea level pressure and {OHC} patterns associated with the {IPO} phase transition around 1998. {T}he negative {IPO} phase (1998-2012) is associated with a global ocean heat redistribution. {T}he anomalously cold tropical {P}acific {O}cean leads to an increased oceanic uptake in this region, and a global {OHC} increase of 4x10(22) {J}. {T}he cold equatorial {P}acific also forces mid-latitude wind changes through atmospheric teleconnections, leading to an enhanced wind-driven heat transport convergence at 40 degrees {N} and 40 degrees {S}. {E}nhanced {P}acific easterlies also yield an enhanced heat transport to the {I}ndian {O}cean via the {I}ndonesian throughflow. {A}s a result, the anomalous {P}acific heat uptake is entirely exported towards the {N}orth {P}acific (similar to 50%), {I}ndian (similar to 30%) and {S}outhern (similar to 20%) {O}ceans. {A} significant fraction of this heat is released back to the atmosphere in the {N}orth {P}acific and {I}ndian basins, and transported across 31 degrees {S} in the {I}ndian {O}cean. {O}verall, {OHC} increases most in the {S}outhern {O}cean (similar to 60% of global changes) and northern {P}acific (similar to 40%), with negligible changes in the {I}ndian and {A}tlantic basins. {T}hese results point to the major importance of oceanic circulation in re-distributing the {P}acific heat uptake globally during negative {IPO} phases.},
