摘要：

A single functional approach is used to treat the problem of the diffusion of tracers in a random velocity field posed in a general form. Approximate methods leading to various approximations and the conditions of their validity are discussed. Plane parallel average flow is considered in detail and some features of statistical solutions for the simplest case of it are discussed.
