Fig. 6: Anomaly correlation skill of the area-averaged VPD in the southwest US.

A same as Fig. 4B, but using historical runs taken from SPEAR large ensembles (LE) as the data library to search for the initial model-analogs. B The skill difference between the SPEAR-LE and SPEAR piControl. The stipple indicates the difference is statistically significant (p < 0.05) following Fisher Z-transformation test.
