(a) Composite map of monthly detrended NPPA (shading), SSTA (red contours, every 0.5 °C) and ERA5 wind stress (arrows) computed from peak months of six extreme low NPP events (2005; 2008; 2010; 2020; 2021 and 2023). Shaded areas (NPPA), contours (SSTA) and black arrows (wind stress) displayed in (a) are statistically significant at 95% confidence level. (b) Time series of composite anomalies of the CDNI-averaged: SSTA (solid red line), NPPA (green line), meridional wind stress anomalies (TYA, blue line), sea level anomalies (SLA, orange line), model potential temperature anomalies at 10 m (PT10A, dashed red line) and model mixed layer depth (MLDA, gray line). The composite anomalies displayed in (b) are relative to the peaks of the extreme low NPP events, ranging from 3 months before to 3 months after those peaks. Values significant at the 95% confidence level are denoted by a filled circle.
