摘要: Abstract Combining sea level anomalies with the mean dynamic topography derived from geoid of EGM08 global gravity field model and CLS01 surface height, this study examined characteristics geostrophic currents seasonal interannual variabilities velocity Kuroshio (the source extension). The patterns we actual ocean circulation are basically same. is high in winter low fall, its variability accounts for 18% total change. extension summer winter, 25% significant. ENSO index inversely correlated. However, relationship between not clear. Overall, increases when La Nina occurs decreases El Nino occurs.
