In Ref. <ref>[http://www.iop.org/EJ/abstract/-search=68892777.7/0741-3335/51/6/065007 I. Calvo et al., Plasma Phys. Control. Fusion 51 065007 (2009)]</ref> we have formulated a phenomenological model which based on the paradigm of flow shear generation by Reynolds stress and turbulence supression by shear. We suggest that the experimental results might be an indirect evidence of the development of poloidally asymmetric zonal flows. | ||
