Dynamics of zonal flow excitation in tokamak plasmas is investigated based on the resistive interchange mode turbulence. Employing low freedom approach, the resistive interchange mode turbulence zonal flow system is solved both analytically and numerically. Our results show that the large scale zonal flow or oscillating zonal flow can be excited in the case of sufficiently high pressure gradient (driving force).
