In the present paper the AA. reported some phenomena
observed in a parallel light beam which propagated in the lower atmosphere.
This beam was observed on a plane screen normally crossing the beam. Por
some source-screen distances a cellular intensity distribution was noted:
this structure was moving with the wind speed.
In order to explain these phenomena the AA. suppose an atmospherical
turbolence model based on the eddies with an optical inhomogeneity, which
have a spherical symmetry. This inhomogeneity produce a beam focusing
only at a give distance depending upon inhomogeneity characteristics.
The focusing forms a luminous ring which can be considered the source
pseudoimage made by the eddies
