Outline Activities
"Modeling of the Internal Waves in the Ocean"
Internal waves in the ocean has large amounts of energy and plays some important roles in the ocean processes. Using the ocean model its detail in specific sea areas are investigated.

"Nonlinear Wave Phenomena in Fluid"
While the nonlinear phenomena take on highly complex aspect, there are some coherent structure --- vortex, solitary wave etc. My research aims to understanding of this structure. I investigate, theoretically,numerically and experimentally, two-dimensional interaction of the solitary waves and waves generated in the flow by topography etc.
