Abstract: Accretion onto supermassive black holes can proceed in different regimes. When the accretion rate significantly exceeds the Eddington limit, the innermost part of the disk inflates as the radiation pressure becomes dominant and mass loss in the form of a radiation-driven wind occurs. I will present the results of an investigation of the effects of these winds on clouds of the broad line region that surrounds the central engine of the AGN. Nonthermal radiation is produced by particles locally accelerated in the bowshocks formed around the clouds. This emission can explain the nuclear radio core observed in some Seyfert galaxies where no jet is present.
