Extended Data Fig. 5: Meridional structures of \({\overline{{{{\mathbf{SSH}}^{\prime}}}}_{\boldsymbol{y}}^{\mathbf{2}}}\), EKE, surface zonal current, and SST trends.
From: Intensification of Pacific tropical instability waves over the recent three decades
Left/right panels are trends/mean over 1993–2021, averaged between 160°W–100°W. a,b, \({\overline{{{\rm{{SSH}}^{\prime}}}}_{{y}}^{{2}}}\). c,d, EKE. e,f, surface zonal current. g,h, SST. They are on the basis of satellite observation or derivation (red), GLORYS12V1 reanalysis (magenta), and OFES2 simulation (blue). Black curve in f denotes surface zonal currents from historical drifter trajectories66. Trends marked with circles pass the 95% confidence level based on the modified Mann–Kendall test.
