Fig. 4: Changes in interbasin heat exchanges.
From: Mitigation-driven global heat imbalance in the late 21st century
Changes in annual mean meridional OHT (∆OHT), the components due to ocean circulation alteration (\(\Delta {\overline{{OHT}}}_{{v}^{{\prime} }}\)) and ocean temperature alteration ((\(\Delta {\overline{{OHT}}}_{{\theta }^{{\prime} }}\)) and the residual term (Res) due to the effects of eddies, diffusion and the non-linearity resulting from ocean circulation and temperature changes across the boundaries between the Atlantic and the Southern Oceans (a) and between the Indo-Pacific and the Southern Oceans (b) in the mean of 2051–2100 relative to the mean of 2041-2050 in the 8-model SSP534OS simulations. c, d As in a, c and b, d but for changes in the SPEAR SSP534OS (red), SSP534OS_StrongAMOC (blue) and SSP534OS_EStrongAMOC (green). Results are illustrated as multi-model mean (MMM: dot) ± one standard deviation among models (bars) as well as for each model (colored cross) in (a, b). Results are illustrated as ensemble mean (dot) ± one standard deviation among ensemble members (bars) for each simulation in (c, d). Positive (negative) values indicate anomalous northward (southward) OHT.
