[en] Anomalous transport mediated by drift wave turbulence has been studied by many authors using weak and renormalized turbulence theory. Additional nonlinear effects coming from three-wave coupling have been studied in simple models by Waltz and for drift waves by Waltz and Dominguez. At the same time, the ''clump'' theory of Dupree has been extended and applied to drift wave turbulence. In the present work, we discuss how the discreteness effects associated with clumps may be combined with the nonlinear wave coupling formalism. It is shown that both the nonlinear wave coupling and clump correlation act as sources for the spectral density in k, and w, with a comparison between the two effects being presented. 5 refs
