The general theoretical framework also addresses the interactions of SAW/DAW including drift waveturbulence(dwt)withzonalstructures(zs;i.e.zonalflowsandfields)andphasespacezonal structures (PSZS) [34]. Such interactions of SAW/DAW/DWT with ZS/PSZS involve cross%scale couplingsmeso%scaledynamicsandnon%localtransport[3;zarzosoetal.prl& 110125002(2013); Dumont et al. PPCF 55 124012 (2013)].
