Zonal flows are now widely recognized to be a key phenomenon for understanding of fluctuation-induced transport in magnetically confined plasmas. The existence of the zonal flows has been directly identified by the measurement of electric-field fluctuations as well as of bicoherence of drift-wave turbulence which introduces the energy transfer from drift waves to zonal flows via three-wave interactions. The appropriate diagnostic methods for these subjects are introduced.
