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(r₁) − θ(r₂) (for separations r₁ − r₂ lying in the convective interval) are found.
