Fusion plasma turbulence often shows self-organized turbulent structures such as zonal flows. This phenomenon has been is discussed by analogy with a self-organization picture described by the Hasegawa-Mima (H-M) equation. Although the H-M equation predicts several important features such as the dual cascade of turbulent spectra, the Rhines scale, and the adiabatic response scale, these basic features have not examined in fusion plasma turbulence so far. In this talk, we present the self-organization of electron temperature gradient driven turbulence, examine these basic features, and discuss their impact on turbulent transport.
