Outline of Final Research Achievements

The Indonesia Throughflow (ITF) is thought to induce changes of sea surface temperature (SST) and water-mass transformation in the Indonesian Sea and hence control the basin-scale climate change. In the present study, a high-resolution numerical experiment is carried out to quantify tidal mixing in the Indonesian Archipelago and its effect on the ITF. The validity of the calculated results is confirmed through the comparison with the results of previous microstructure observations. It is shown that significant changes of SST and water-mass transformation occur along the eastern route of the ITF caused by vertical mixing associated with breaking of internal tides near constricted channels as well as horizontal mixing associated with sub-mesoscale eddies with diameters of several kilometers.
