| Outline of Final Research Achievements |
The objective of this research project was to study the dynamics and singularity of flow structures such as vortices and waves in turbulence using a large scale computer simulations. We placed astrophysical- and geophysical turbulence as the main research target because the anisotropy of flow structures plays the essential role in them. As the major achievements of the project, we can raise (1) clarification of the mechanism of development of the energy spectrum for stably stratified turbulence, and (2) understanding of singularity and characteristic geometrical features in the vortex reconnection process. In particular, it is realized that the second result is largely related to the problem of regularity of the Navier-Stokes equations, one of the seven millennium problems by the Clay Mathematical Institute.
