Statistical description of the diffusion of a passive tracer in a random velocity field

A M Obukhov Institute of Atmospheric Physics, Russian Academy of Sciences, Pyzhevskii per. 3, Moscow, 109017, Russian Federation

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