The self-organizing map method is applied to satellite-derived sea-level anomaly fields of1993-2012 to study variations of the Kuroshio intrusion northeast of Taiwan Island.Four major features are revealed,showing significant seasonal variability of the intrusion.In general,the intrusion increases(decreases) with a high(low) sea-level anomaly at the edge of the East China Sea shelf in winter(summer).Open-ocean mesoscale eddies play an additional role in modulating the seasonal variation of the intrusion.Further analyses are needed to study eddy-Kuroshio interaction dynamics.
