 Large-scale percolation and diffusion in turbulent stratosphereA. Bershadskii Physica A: Statistical Mechanics and its Applications, 1994, vol. 206, issue 1, 120-126 Abstract: A simple model analyzing the properties of “fast” components of turbulent diffusion is proposed in order to explain two different regimes of large scale transfer of a passive scalar observed in the stratosphere. It is argued that these “fast” components are directly related to percolation of the passive scalar in a turbulent fractal and that there exist two spectral power laws for fluctuations of the passive scalar: the “-53” Corrsin-Obukhov law and a “-43” law. These two laws correspond to different fractal structures (backbone and elastic backbone) of the field of the passive scalar. A good correspondence is found between the spectral and fractal scaling laws and the experimental data for the stratosphere as well as known percolation parameters. It appears that some percolation parameters in quasi-two-dimensional turbulent percolation are similar to those of three-dimensional turbulent percolation rather than those of the two-dimensional one.
