Abstract
A two-particle stochastic model of turbulent dispersion in the classic al isotropic pseudoturbulence is suggested. The main idea is to descri be the relative motion of two particles in small scales by a stochasti c differential equation, while the dispersion in large scales is gover ned by the Eulerian stochastic model. This leads to the nice property of the new model: in small scales it describes properly the Richardson cubic law, and at large scales it approximates well the ''two-to-one' ' reduction principle.
