It is well-known that rotating stellar convection transports angular momentum equatorward while a thermal energy flows poleward producing warm poles. The characteristic equatorial acceleration of the solar rotation law is a consequence of these phenomena. New numerical box simulations confirm the cross correlations $\langle u_r u_\theta\rangle $ and $\langle u_\theta u_\phi\rangle $ to be anticorrelated but their signs prove to be different for slow and fast rotation. The explanation is that… CONTINUE READING
