- Assistant Professor
| Affiliation | Graduate School of Advanced Science and Engineering |
|---|---|
| Discipline | Integrated Engineering |
| Academic Degrees |
Kyushu University Doctor of Science |
| Research Fields |
Mathematical and physical sciences; Earth and planetary science; Meteorology / Physical oceanography / Hydrology |
| Research Keywords | Kuroshio frontal waves, kyucho, internal Kelvin waves, bottom intrusion, the Bungo Channel / geostrophic turbulence, inverse cascade of energy, ageostrophic instability, loss of balance / tidal mixing, tidal front, the Bungo Channel / tidal vortex, the Seto Inland Sea, the Neko-Seto Strait / Kuroshio, Bifurcation Current, the Kii Channel |
| Comments | My research fields are geophysical fluid dynamics and physical oceanography. In recent days, I am studying the influences of the Kuroshio on coastal oceans (especially, Kuroshio warm water tongues and kyucho), tidal mixing and tidal fronts, the influences of ageostrophic, unbalanced disturbances on the inverse cascade process of energy in geostrophic turbulence. My main method of research is numerical procedures using relatively simple numerical models in order to understand underlying physical processes and mechanisms of above oceanic phenomena. |
