The simulated trends of the PWC over the tropical Pacific in atmospheric model experiments. a Shows the simulated climatology (contours) and the trend (color) of the mass stream function of the PWC in the pan-tropical-ocean forcing atmospheric model experiments, with d–f showing the simulated PWC trends in the tropical Atlantic-, the tropical Pacific-, and the Indian Ocean-forcing experiments. The gray dots cover the areas with confidence level of 95%. b Shows the additive effect of the three simulations as shown in d–f, which is very similar to the model results driven by the pan-tropical oceans (a), implying the linearity between the SST forcings from different tropical ocean basins. c Quantifies the trends of the PWC in each of the four atmospheric model experiments, with black bars showing the amplitude of the trend and the error bars indicating the 95% confidence intervals. g–i Quantify the westward shifts of the west edge (c), the center (d), and the east edge (e) of the PWC in these atmospheric model simulations
