The equations of motion for point vortices in a two-dimensional square doubly periodic domain are derived from those for an open domain. The ...

These vortices often occur with strong, environmentally induced anisotropy in their velocity and vorticity fields. We propose a definition of the essential characteristics of coherent vortices and formulate hypotheses concerning their dynamical role in complex, anisotropic fluid motions. Finally, we analyze numerical solutions both for uniformly rotating, stably stratified three-dimensional flow and for two-dimensional flow for the phenomena of enstrophy cascade and dissipation, intermittency, isotropy in the appropriate coordinate frame, coherent vortex emergence, vortex population dynamics, and approach to a nonturbulent end state.

As the coupling is weakened, the systems ...

This work examines the statistics of persistence, with particular focus on the phase-of-year-dependent pattern ...
