We describe diffusion processes when aerosol particles are moving in the atmosphere. The impact of particles' inertia and diffusion coefficient on multistream formation was determined via the numerical solution of the Fokker-Planck equation. The simulation has been performed within the certain range of parameters, considering turbulent diffusion effects in real atmospheric conditions. The results of the study may be useful in interpreting aerosol optical sensing data.
