In turbulent planar Couette flow under anticyclonic spanwise system rotation, large-scale roll-cell structures arise due to a Coriolis-force-induced instability. The structures are superimposed on smaller-scale turbulence, and with increasing angular velocity ( $\unicode[STIX]{x1D6FA}_{z}$ ) such roll cells dominate the flow field and small-scale turbulence is instead suppressed in a certain rotation number range $0
