Rotating Magnetized Spherical Couette : mode regime

Meridional cross section of a flow at Ro=-1.2, f_o = 10 Hz. The upper left shows the angular velocity of the flow in a meridional plane rotating at 0.85 Δf relative to the outer sphere. The mean flow has been subtracted off in this figure. The azimuthal magnetic field at the surface of this plane is represented by the blue line. The upper right shows the (cylindrically) radial velocity field in the same plane with the latitudinal magnetic field represented at the surface. In this figure the map includes the mean flow as well as
the fluctuations. The grey lines represent streamlines of the mean poloidal circulation. The time series at the bottom represents the kinetic energy in each of the first 3 principle components as a function of time. This is the same as Fig. 6d. The vertical line indicates the time of the frame.
