Subcritical turbulent condensate in rapidly rotating Rayleigh–Bénard convection
Subcritical turbulent condensate in rapidly rotating Rayleigh–Bénard convection
The possibility of subcritical behaviour in the geostrophic turbulence regime of rapidly rotating thermally driven convection is explored. In this regime a non-local inverse energy transfer may compete with the more traditional and local direct cascade. We show that, even for control parameters for which no inverse cascade has previously …
