Turbulent scaling in rotating spherical Couette flow

We study the parameter dependence of torque and other flow quantities in rapidly rotating spherical Couette flow with radius ratio $\eta = r_{\mathrm{i}}/r_{\mathrm{o}} = 0.35$ using the University of Maryland 3m system. We examine the dependence of the dimensionless torque, $G = T/\rho\nu^2 L_{gap}$, on the Reynolds number, $Re = \Delta\Omega L_{gap}^2/\nu$, and Rossby number, $Ro = \Delta\Omega/\Omega_{\mathrm{o}}$, for $-5
