a ACC, MSSS, and RPC of MME SSTA predictions at a one-year lead time (YR1). Dotted regions denote where ACC and MSSS are significantly greater than 0, or RPC is significantly different to one at the 95% confidence level. Note that RPC is calculated only when ACC is positive. The regions with negative ACC are masked out as they imply no predictive skill. b, c, and d Same as (a) but for MME SSTA predictions at two-year (YR2), three-to-four-year (YR3–4), and five-to-nine-year (YR5–9) lead times, respectively. A non-parametric bootstrap method is applied to test statistical significance.
