Abstract

Abstract

The salinity variability on the interannual time-scale is analyzed using SODA data by EOF statistical method.The results show that there is high correlation coefficient between interannual variation in the sub-surface salinity and ENSO.The signatures have a pan-longit udinal "seesaw" feature.The factors including zonal advection,meridional advection,vertical movement and fresh water flux anomalies were analyzed.The difference among these factors,which play important roles for surface and sub-surface salinity variations,was investigated.It was shown that the zonal advection anomalyis a more important factor in the surface but the vertical movement anomaly for the sub-surface regarding salinity variability on the interannual time-scale.
