A model of distribution over angles of deviation from the horizontal position of crystal cloud particle maximal diameters in the process of their gravitational sedimentation is proposed. A single-parametric distribution over orientation angles is obtained. The distribution parameter is shown to depend on the particle size and the rate of energy dissipation in the turbulence cells.
