| 英文摘要 | Variability of two Paci fi c western boundary currents (WBCs)- the Kuroshio and the Mindanao Current- during the strong 2010/11 La Nifia event is investigated using ship-based hydrographic observations and moored currentmeter data collected off the east coasts of the Philippines. The geostrophic currents calculated using the hydrographic data show that, during the 2010/11 La Nifia winter, the Kuroshio decreased by- 10 Sv (1 Sv ; 10 6 m 3 s 21 ), whereas the Mindanao Current increased by- 5 - 10 Sv, relative to the normal winter in late 2012. The interannual variability based on the hydrographic data is con fi rmed by moored current-meter measurements and satellite altimeter geostrophic currents. A coastally trapped Kelvin wave model is used to explain the interannual variability of the two WBCs during the different ENSO phases. The good comparison of the simulated sea level anomalies around the Philippines with the altimeter data suggests that the interannual variability of the WBCs is associated with Kelvin wave propagation from the Sulawesi - Sulu Seas clockwise around the Philippine Archipelago. We identi fi ed that the Kelvin waves are excited by downwelling equatorial Rossby waves propagating into the Indonesian Seas during the La Nifia. The transport anomalies of the WBCs are comparable to the total meridional transport anomalies integrated across the interior North Paci fi c Ocean, suggesting the importance of the WBCs in the heat charge - discharge processes of the western Paci fi c warm pool during ENSO events. |
