Scientific paper

Vortex steets were revealed in satellite measurements in the helisophere. They can efficiently affect energetic particle transport. Numerical study of cosmic ray diffusion in a presence of a layer of vortex flows is performed. Random phase linear waves with a power-law spectrum are introduced to the system. This model represents a mixture of coherent structures which belong to strong turbulence and weak turbulence effects in the medium. Different diffusion regimes, i.e. classical diffusion, subdiffusion and superdiffusion, are analyzed. Importance of regular and stochastic components is studied. Comparison with theoretical estimates for radial transport coefficients is made.
