Fig. 2: Robust zonal-mean impacts of constraining Pacific SST trends through hindcast conditioning and pacemaking resemble ENSO variability.
From: Robust impact of tropical Pacific SST trends on global and regional circulation in boreal winter
Impact of constraining tropical Pacific SST trends (ΔPac) on the zonal-mean DJF temperature trend (1981/82-2018/19) from (a) hindcast conditioning and (b) pacemaking. d, e Similar results to (a, b), but on the zonal wind trend. c, f Similar to (a, b) and (d, e) but for ENSO response (ΔENSO) in reanalysis (ERA5). Stipples indicate statistically significant impacts at the 5% significance level. The blue dashed vertical lines in (a) and (b) show where the tropical temperature is averaged in Fig. 5.
