MA, TD, ZA, TH, and EK (1/year) represent mean currents damping, thermodynamic damping, zonal advective feedback, thermocline feedback, Ekman (upwelling) feedback, respectively. BJ (1/year) is the sum of these five terms. Red bars are ANTSIlate21 minus ANTSIhist, and blue bars are ANTSI4CO2 minus ANTSIhist.
