Abstract

The strong reduction in the fluctuation-driven particle flux in the presence of zonal flows was experimentally studied. Zonal flows were shown to change statistical properties of the fluctuations due to the randomization of phases of coherent structures dominating spectra. These observations are qualitatively consistent with the model of the random Doppler shift of the turbulent structures by zonal flows.
