The strong flow shear suppresses the radial transport of pressure filaments, and the pressure profile in the pedestal region is partially recovered. As a result, a secondary instability is quasilinearly excited, which yields a secondary collapse. The subsequent damped oscillation is also analyzed by phase diagram analysis.}, title = {Interplay between fluctuation driven toroidal axisymmetric flows and resistive ballooning mode turbulence}, volume = {26}, year = {2019} }
