Extended Data Fig. 4: Model skill (CESM SMYLE relative to observations) and model predictability (CESM SMYLE relative to SMYLE FOSI).
From: Multi-month forecasts of marine heatwaves and ocean acidification extremes

Comparison of (column 1) model skill (CESM SMYLE relative to observations) and (column 2) model predictability (CESM SMYLE relative to SMYLE FOSI) for 20 ensemble members from CESM SMYLE at 1.5 (a-b), 3.5 (c-d), 6.5 (e-f), and 10.5 month lead-time (g-h). Skill scores range from -1 to 1, with SEDI score close to -1 being unskillful, SEDI score of 0 being no better than random forecasts, and SEDI score of 1 being perfect skill.
