摘要：

We consider advection of a passive scalar theta(t, r) by an incompressible large-scale turbulent flow. In the framework of the Kraichnan model all PDF's (probability distribution functions) for the single-point statistics of theta and for the passive scalar difference theta(r(1)) - theta(r(2)) (for separations r(1) - r(2) lying in the convective interval) are found.
