Fig. 3: SST and precipitation in the eastern equatorial Pacific.

Scatterplots of monthly SST versus monthly precipitation in the Niño-3 region for a piControl, b HIST-AER, and c HIST-GHG simulations. Orange dots represent cases when precipitation is larger than 5 mm/day. The red vertical dashed line represents the critical temperature for convection. The black vertical and horizontal dashed lines denote the climatological mean values of SST and precipitation, respectively.
