摘要：
快速旋转 Rayleigh-Bénard 对流的热输运对许多地球物理流动至关重要。实验室测量受到沿垂直壁面发展的强壁面模态阻碍，显著干扰热通量。我们证明垂直壁面上的窄水平鳍片能有效抑制壁面模态，确保其对全球热通量的贡献在地转状态下与体对流相比可忽略，为旋转对流地球物理相关状态的新实验研究铺平道路。
英文摘要：
The heat transport by rapidly-rotating Rayleigh-Bénard convection is of fundamental importance to many geophysical flows. Laboratory measurements are impeded by robust wall modes which develop along vertical walls, significantly perturbing the heat flux. We show that narrow horizontal fins along the vertical walls efficiently suppress wall modes ensuring that their contribution to the global heat flux is negligible compared with bulk convection in the geostrophic regime, thereby paving the way for new experimental studies of geophysically relevant regimes of rotating convection.
