| 英文摘要 | Conductivity-temperature-depth(CTD)data obtained during the 2010 La Ni?a winter and the 2012 normal winter,combined with concurrent Argo profiling float data,provide a quasi-synoptic description of the water mass distributions and their variations in the far western equatorial Pacific Ocean.The water mass connection between the western Pacific and the east Indonesian seas is emphasized.Analysis indicates that the North Pacific Tropical Water(NPTW,S>34.9)carried by the Mindanao Current southward and the South Pacific Tropical Water(SPTW,S>35.1)from the southern hemisphere meet in the area.Observations suggest that the southward transport of the NPTW is stronger in 2010 than in 2012 due to enhanced advection of the Mindanao Current.The distribution of SPTW,which crosses the equator in the northwest direction and retroflects back to the interior Pacific Ocean,is found to retreat from 4°–5°N in2012 to 2°–3°N in 2010 La Ni?a peak in the 130°E section.A relatively fresh tropical subsurface water is identified in between the NPTW and the SPTW,moving eastward with the North Equatorial Countercurrent into the equatorial Pacific Ocean.However,the salinity maximum of this subsurface fresh water is found to decrease eastward,suggesting that the salinity maximum is generated either by strong diapycnal mixing or by isopycnal mixing of temporally entrained Indonesian sea water into the area. |
