摘要	Based on monthly mean Argo profiler float data from 2004 to 2008 and monthly mean sea surface height and current velocity data from the Simple Ocean Data Assimilation (SODA) reanalysis for the period 1958-2007, the three-dimensional structure of the Mindanao Eddy (ME), its seasonal and interannual variability, and its impact on the thermohaline structure are analyzed. In addition, the displacement of the ME centre and its relation to ocean circulations are also discussed. The results showed that the ME spreads vertically from about 600 db depth upward to about 40 db depth. In addition to its strong seasonal variation, the strength of the ME displays strong interannual variability resulting from the interannual variability in the North Equatorial Current (NEC), the North Equatorial Counter Current (NECC) and the Mindanao Current (MC). The meridional movement of the centre of the ME has strong seasonal and interannual variability, and the zonal movement has a strong seasonal variation. The meridional movement is associated with the meridional displacement of the interface between the NECC and the NEC, whereas the zonal movement is associated with the zonal displacement of the interface between the MC and the northward branch of the NECC. The ME variability can greatly affect the pattern of the thermohaline structure in the local upper ocean. When the eddy is strong, the cold and low salinity water within it moves vigorously upward from the deep layer; the thermocline shoals significantly; the subsurface high salinity water shows a large decrease; and the upper mixed layer becomes thinner, and vice versa.
