• Dynamics of Submesoscale Processes in the Ocean: Effects of Narrow Fronts and Bottom Topography

  Project Period (FY)： 2021/04  -  2025/03  Investigator(s): Tanaka Yuki

  Grant-in-Aid for Scientific Research(C)  Principal Investigator  21K03664 

  This study aims to elucidate the generation mechanisms and physical properties of submesoscale processes in the ocean. Specifically, it clarifies the growth rates and spatial structures of mixed-layer and symmetric instabilities in realistic narrow fronts, such as those found in the Kuroshio and Kuroshio Extension regions, through a linear stability analysis within a two-dimensional cross-section. The dependence of these properties on the intensity of the fronts is also examined. Furthermore, the study focuses on topographically trapped internal tides, introducing a new energy diagram that incorporates a “topographic mode,” which represents an internal mode with a barotropic vertical structure. This diagram enables more accurate estimation of the generation rates of subinertial internal tides, including diurnal internal tides in mid- to high-latitude regions, which have been significantly underestimated in previous studies.
