a normalized pressure perturbation; b normalized turbulence intensity flux. Here \(\delta p,{p}_{{ped}}\) and \({\delta v}_{r}\) are the perturbed pressure, equilibrium pedestal top pressure, and perturbed radial velocity in BOUT + + modeling. The horizontal axis is the time in Alfvén time, and the vertical axis is the normalized poloidal magnetic flux. The horizontal dashed line indicates the location of the separatrix. c The time-averaged pressure perturbation (blue) in the saturation phase. d The time-averaged turbulence intensity flux (blue) in the saturation phase, and normalized by its radial maximum absolute value; radial skewness of the pressure perturbation (red).
