Geophysical and astrophysical fluid flows, e.g., in planetary interiors, are typically driven by convection and often constrained by planetary rotation at large scales. Rapidly rotating Rayleigh-Bénard convection (RRRBC), a rotating fluid layer heated from below and cooled from above, provides a paradigm for direct numerical simulations (DNS) and laboratory studies of such flows, but current state-of-the-art techniques cannot achieve realistic strengths of rotational effects. Remarkably, taking advantage of the characteristics of rapidly rotating thermal convection leads to a new numerical approach that relies on appropriately rescaled equations, and enables exploration of this very wide parameter range. I will present the first DNS of rapidly rotating convection at realistic rotation strengths (very small but finite Ekman/Rossby numbers) using this approach, revealing new physics in this previously inaccessible parameter regime, including an emergent symmetry between cyclones and anticyclones, efficient heat transport and a rich boundary layer structure near the top and bottom of the fluid layer.
