a Inertial activity (IA) index (gray solid line based on PIRATA winds at 11.5°N, 23°W, black solid line based on CCMP winds at the grid point 11.125°N, 23.375°W) from August 30 until October 1 including the observed near inertial wave event around September 15. The colored lines mark different thresholds α for IA. Gray shading highlights the boreal summer season July–September (JAS). b Seasonal cycle of monthly prevalence for IA (based on CCMP winds at the grid point 11.125°N, 23.375°W) crossing the different thresholds α, normalized by their respective annual means (0.14, 0.045, and 0.02) for comparison. c Seasonal cycle of monthly prevalence for IA crossing the threshold α = 2 (as in b), but without normalization. d Seasonal cycle of the mixed layer depth (MLD) from ePIRATA at 11.5°N, 23°W.
