A study was performed on mean shear flows, zonal flows and generalized Kelvin-Helmholtz modes in drift wave turbulence. A minimal model for the L→H (low- to high-confinement) transition was proposed, which involved the amplitude of drift waves, zonal flows and the density gradient. The effect of poloidally nonaxisymmetric structures on anomalous transport was investigated.
