Rayleigh-benard thermal convection
WebNote that large-scale flow in Rayleigh–Benard convection exists not only in the´ very turbulent state but also near the onset of convective motion where the Rayleigh number Ra is just above the critical value for convection.

This approach is given by the problem of rotating Rayleigh-Bénard convection (RRBC) : a rotating fluid layer heated from below and cooled from above. For large-scale systems, the governing parameters of RRBC take extreme values, leading to a regime of geostrophic turbulence.
