Research

Shin-ichi Takehiro is working on geophysical fluid dynamics. His research interest covers all kinds of problems related to fluid motions in planetary surfaces and interiors (atmospheres, mantles, and central cores), as well as problems of the Earth's atmosphere and ocean. He also extracts more general fluid dynamics problems, such as the subject of waves and shear instability, through the analysis of systems extracted from natural phenomena. He is not only good at numerical calculations but also at building intuitive theoretical models to understand the results of numerical experiments. He also develops techniques and software for numerical methods to deal with various problems in geophysical fluid dynamics. Recent topics of his research are as follows.

1) Atmospheric motions of the planets in the solar system and exoplanets.
2) Thermal convection in stellar interiors.
3) Penetration of convection into a stable layer in general.
  Typical cases include vigorous mixing by turbulent convective motion,
  and slow penetration of columnar motion affected by rotation.
4) Thermal convection and MHD dynamos in rotating spherical shells.
5) Waves, mean flows, and shear instability.
