[ACG33-04] Formation mechanism for the North Pacific Transition domain SST and SSS fronts
Keywords:bottom topography, SST front, SSS front , Subtropical-Subarctic Seawater exchange
The buoy trajectories and the modelled trajectories captured the flow structure (i.e. front structure) in detail. They suggest that the flow structure in the transition domain is dominated by low rise bottom topography. We also showed mixing ratio of the subarctic and the subtropical seawater in the Transition domain using the particle tracking. In addition, it was also found that the place where the sea water tends to stagnate well corresponds to the place where the SST deviation appears due to the variation of the Isojet jet J1 indicated by Mitsudera et al. (2018).
