Abstract

A hypothesis is made that optical anisotropy of clouds in the atmosphere can be implied not only by the shape and the orientation of scattering particles, but furthermore it can be a result of a random non-Poisson distribution of the particles in space. In that way even for water-drop clouds the scattering medium can be appreciably anisotropic if spherical water drops particularly distributed in space. We proposed a heuristic mathematical model of such hypothetical anisotropy on the basis of fractal distribution of particles in space. In addition, we performed a Monte Carlo experiment to study presumable radiation effects caused by "fractal" anisotropy in water-drop clouds.
