Energy cascades in rotating and stratified turbulence in anisotropic domains

The concept of inverse energy cascades has played a central role in the development of turbulence theory, with applications in two-dimensional and quasi-two-dimensional flows. We examine the presence or absence of inverse energy cascades in rotating stably stratified flows constrained to anisotropic yet fully three-dimensional domains, in a range of parameters that are relevant for planetary atmospheres. Our results show that inverse energy cascades can indeed emerge when rotation overcomes a certain threshold that depends on the stratification. Implications for the self-organisation processes of planetary atmospheres are discussed.
