a Spatial patterns of SSH anomalies (shading; m) and the associated geostrophic currents (vectors) for the second cyclostationary EOF (CSEOF) mode derived from ORAS5 reanalysis, shown for boreal winter (DJF), spring (MAM), summer (JJA), and autumn (SON). b Corresponding SSH anomaly patterns obtained from satellite-derived dynamic ocean topography (DOT). c Principal component (PC) timeseries of the interannual mode derived from ORAS5 (solid line) and satellite DOT (dashed line), showing strong agreement between the model and observations (r = 0.89, p < 0.01).
