Extended Data Fig. 6: Example forecast of aragonite saturation state extreme events from the 1999 La Niña.
From: Multi-month forecasts of marine heatwaves and ocean acidification extremes

Forecasts of Ωa initialized during the August 1999 La Niña event. Anomalies (color) and extremes (hatching) in (column 1) from an interpolated observational product (OceanSODA-ETHZ), and (column 2) CESM SMYLE forecasts (a,b) 1.5, (c,d) 3.5, and (e,f) 5.5 months after initialization. Extreme events are defined in observations (below the 10th percentile) and in CESM SMYLE (below the 10th percentile in a minimum of 50% of ensemble members).
