Turbulence

Large-scale structures, waves and vortices coexist in anisotropic turbulence systems.  We are trying to elucidate the generation and maintenance mechanism of the coexistence of these different kinds of turbulence.

Gravity waves with broad-band spectra can be observed on the surface and inside of the ocean, and in the atmosphere, and are turbulent flows (in a broad sense).  We are working on energy transfer between waves, which is one of the important elements of atmospheric and oceanic flows.

While long-term prediction of chaotic turbulence is impossible, short-term prediction can be done with sufficient accuracy.  Our goal is to predict turbulence using machine learning and to control turbulence using the prediction results.
