layer of its fluid rotating about the vertical axis. In the rotating regime studied here, with
Rayleigh numbers of order, convection takes the form of columnar vortices, the number and
size of which depend upon the Ekman and Prandtl numbers, as well as the geometry–
periodic or confined. As the Ekman and Rayleigh numbers vary, the number and average
area of vortices vary in inverse proportion, becoming thinner and more numerous with …
