Fig. 3: Meridional evolution of SWP SST signal.
From: Cross-hemispheric SST propagation enhances the predictability of tropical western Pacific climate

The propagation of SWP SST signal indicated by the lagged correlations of the MAM SWP index with zonally averaged SST (115°E–160°E) in the following consecutive-3 months. a is the observation, b and c are for pacemaker experiment and SOM multi-model ensemble mean, respectively. The dotted shading in a and b indicates the correlation is significant at the 95% confidence level.
