We experimentally investigate turbulent rotating Rayleigh-Bénard convection in an upright cylinder. Particle image velocimetry measurements are carried out in a planar cross-section of a water-filled cylinder with diameter-to-height aspect ratio Γ = 1/2. In comparison with previous measurements in Γ = 1 convection cells there are remarkable differences in flow structuring which may be attributed to the closer proximity of the sidewall. We quantify the dynamics of the large-scale circulation at low rotation rates and the spatial distribution of the vortical plumes at higher rotation rates.
