| Research Abstract |
This study analyzed ocean data assimilation and quasi-coupled data assimilation results, and found that the variation of trade winds associated with El Nino and La Nina causes change of saline water advection from south and evaporation in the equatorial Pacific, and results in the salinity variation. This variation induced the change of vertical mixing and affected the near-surface temperature. Improvements were required for the evaluation of the influence of the salinity variation on the atmospheric fields.
