The main consequences of "hot" scheme for the cumulative effect are considered: the universality of inclusive spectra slope, the dependences of these spectra on the emission angle and the sort of a hadron. The general model of a "hot" source of cumulative particles is given, which sums the contributions of the nuclear density fluctuations and temporal fluctuations of production process development to the cross section of collective interactions of the nucleons. The information gained from the experimental data on the cumulative effect is discussed.
