We review the analytical methods of solving the stochastic equations for barrier-type dynamical behavior in plasma systems. The path-integral approach is examined as a particularly efficient method of determination of the statistical properties.
We propose a new phenomenology of the generation of internal transport barriers, based on the exact periodic solution of the Flierl-Petvishvili equation. We examine the stability of this solution and compare the late stages of the flow with the ensemble of vortices.
We use a systematic method which allows us to identify a class of exact solutions of the Flierl-Petvishvili equation. The solutions are periodic and have one dimensional geometry. We examine the physical properties and find that these structures can have a significant effect on the zonal flow generation.
