Abstract
Two-layer tidal modeling has been carried out in order to investigate the generation feature of the M2 internal tide in the East/Japan Sea, and some preliminary results are shown in the presentation. Considering the internal tidal length is several tens of km, the grid interval was set to be 1/64° in latitude and 1/48° in longitude. 15 M2 cycle was calculated to see what the generation mechanism is in the model region. Model result show that there are several generation region in the East/Japan Sea and one of the representative generation region is Yamato Rise, from which the generated internal tide is emanating several hundreds of km distance in northwest and southeast directions. One ray of internal tide propagation also appears to be the northeastern end of the Korea/Tushima Strait where the inflow of the barotropic energy flux from East China Sea to East/Japan Sea exists, with a large depth gradient.Even though it is a preliminary result, it is quite interesting to note that the amplitude of the M2 interfacial disturbance is large as an order of 10m or so, while M2 surface amplitude is less than 5 cm in most of region. This indicates the possibility of the baroclinic component being large, compared with the barotropic component.
