The standard deviation of SSH computed from Apr 2008–Mar 2009 daily mean fields of GIGATL1 without simulated tides (a) and AVISO (b). Thick black lines show the GIGATL1 domain, and the white box the region for which the Fourier transform is performed for the middle and bottom panels. c The time-mean SSH spectra and a gray straight line for the k−4 slope. d, e Hovmöller plots of the monthly climatological anomalies of the SSH spectra with respect to the mean over the period Apr 2008–Mar 2009 for (d) and 2017–2021 for (e). The respective area-mean T (solid line) plus and minus one standard deviation (dashed lines) are shown in (d) and (e).
