Here, we use an experimental approach to address the questions of zonal jets formation and long-term evolution. A strong and uniform topographic $\\beta$-effect is obtained inside a water-filled rotating tank thanks to the paraboloidal fluid free upper surface combined with a specifically designed bottom plate. A small-scale turbulent forcing is performed by circulating water through the base of the tank.
