Excitation of zonal flow by the modulational instability in electron temperature gradient driven turbulence
Published online by Cambridge University Press: 01 June 2008
Abstract
The generation of large-scale zonal flows by small-scale electrostatic drift waves in electron temperature gradient driven turbulence model is considered. The generation mechanism is based on the modulational instability of a finite amplitude monochromatic drift wave. The threshold and growth rate of the instability as well as the optimal spatial scale of zonal flow are obtained.
