Fig. 5: North Atlantic marine heatwave frequency predictability in dynamic and slab oceans.
From: Ocean dynamics shape marine heatwaves and their predictability
The leading predictable component (APT1) of North Atlantic marine heatwave annual frequency in (a) dynamic and (b) slab oceans, as well as (c) the squared multiple correlation coefficients R2 (dynamic ocean, blue; slab ocean, red). The dashed black line in (c) denotes the 95% significance level. d Lead/lag correlation between Atlantic meridional overturning stream-function and APT1 index for North Atlantic marine heatwave annual frequency. Lags range from −14 to 0 years, in which negative lags indicate that the Atlantic Meridional Overturning Circulation (AMOC) leads the APT index. The stipples refer to the regions where correlations are statistically insignificant at the 95% confidence level. The base map is from NCAR Command Language map outline databases.
