Cyclone-anticyclone asymmetry in rotating thin fluid layers

We report of a series of laboratory experiments and numerical simulations of freely decaying rotating turbulent flows confined in domains with variable height. We show that the vertical confinement has important effects on the formation of large-scale columnar vortices, the hallmark of rotating turbulence, and in particular delays the development of the cyclone-anticyclone asymmetry. We compare the experimental and numerical results face-to-face, showing the robustness of the results.

Automated summary

This study conducted laboratory experiments and numerical simulations to investigate the effects of vertical confinement on freely decaying rotating turbulent flows. The results show that vertical confinement significantly impacts the formation of large-scale columnar vortices and delays the development of cyclone-anticyclone asymmetry. The comparison between experimental and numerical results demonstrates the robustness of the findings.
