Turbulence driven zonal flows play an important role in fusion devices since\nthey improve plasma confinement by limiting the level of anomalous transport.\nCurrent theories mostly focus on flow excitation but do not self-consistently\ndescribe the nearly stationary zonal flow turbulence equilibrium state.\nFirst-principles two-fluid turbulence studies are used to construct a Reynolds\nstress response functional from observations in turbulent states. This permits,\nfor the first time, a reliable charting of zonal flow turbulence equilibria.\n
