Due to the transport modulation induced by Ryukyu Islands, the intraseasonal variation isvery weak in the lower reaches of the Kuroshio in the ECS. A two-layer model reveals the relationamong Kuroshio frontal unstable wave with topography, transport and the axis position of theKuroshio, from which we can infer that the intrusion of intraseasonal long Rossby wave may stimulatethe Kuroshio frontal unstable wave in the upper reaches of the Kuroshio in the ECS. The altimeterdata also shows that the sea level anomaly resulting from intraseasonal long Rossby wave could passthe channel between Taiwan and Ryukyu Islands and propagate northeastward in accord with theKuroshio frontal unstable wave. However, the sea level anomalies passing through the gaps of RyukyuIslands are relative weak and have negligible effects on the Kuroshio variation.展开更多
