Fig. 4: Projected changes in VM and CP SST variability.
From: Enhanced North Pacific Victoria mode in a warming climate
Comparison of the low-frequency VM (a) and CP SST (b) variabilities over the present (1920 to 2000, blue bars) and future (2020 to 2100, red bars) periods in the 30 members of the CESM-LE. The multimember ensemble means over the present and future periods are also shown. Error bars are calculated as 1.0 s.d. of a total of 10,000 inter-realizations of a bootstrap method (see Data and Methods). Members that simulate a decrease are grayed out. Variabilities of the VM and CP SST are projected to increase under greenhouse warming. c Intermember relationships between changes in VM variability and CP SST variability. A linear fit is shown together with the correlation coefficient R, slope, and P values from the regression. Histograms of 10,000 realizations of a bootstrap method for the VM (d) and CP SST (e) variabilities. The gray shaded areas refer to the respective 1.0 s.d. of the 10,000 realizations.
