Fig. 2: Areas of skill.
From: Enhanced multi-year predictability after El Niño and La Niña events
The percentage of global areas (10° × 10° grid cells weighted by cos(latitude)) where the perfect-model predictions exhibit significant skill (the false discovery rate (FDR) is 0.2 when adjusting for the false discovery rate as indicated by the ‘+’ sign stippling in Fig. 1) for predictions initialised in El Niño (red), La Niña (blue), neutral (black), and persistent neutral (yellow) conditions. The shading around each line represents the 5%–95% confidence interval based on 1000 bootstrap realisations (with replacement, see Methods).
