### Abstract

We consider advection of a passive scalar θ(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 θ and for the passive scalar difference θ(r_{1}) - θ(r_{2}) (for separations r_{1} - r_{2} lying in the convective interval) are found.
