| 摘要 | The relationship of the interannual variability of the transport and bifurcation latitude of the North Equatorial Current (NEC) to the El Nino-Southern Oscillation (ENSO) is investigated. This is done through composite analysis of sea surface height (SSH) observed by satellite altimeter during October 1992-July 2009, and correspondingly derived sea surface geostrophic currents. During El Nino/La Nina years, the SSH in the tropical North Pacific Ocean falls/rises, with maximum changes in the region 0-15 degrees N, 130 degrees E-160 degrees E. The decrease/increase in SSH induces a cyclonic/anticyclonic anomaly in the western tropical gyre. The cyclonic/anticyclonic anomaly in the gyre results in an increase/decrease of NEC transport, and a northward/southward shift of the NEC bifurcation latitude near the Philippine coast. The variations are mainly in response to anomalous wind forcing in the west-central tropical North Pacific Ocean, related to ENSO events. |
