Statistics of Turbulence around a Columnar Vortex
Interactions between intense elongated vortices and surrounding turbulent motions are often produced artificially in engineering and environmental flows, and they occur naturally in most homogeneous and sheare...

Statistics of Quasi-Geostrophic Vortex Patches
The statistics of quasi-gestrophic point vortices and spherical vortex patches are investigated theoretically and numerically, in order to understand fundamental aspects of quasi-geostrophic turbulence. The nu...

The Breakdown of a Columnar Vortex with Axial Flow
The interaction between a columnar vortex and external turbulence is investigated numerically. The formation of turbulent eddies around the columnar vortex and the vortex-core deformations are studied in detai...
