Hydrodynamic Model of Spatial and Temporal Variations of Poloidal and Toroidal Components of Three-Dimensional Solar Flows

摘要

Numerical simulation results of the global solar flows are presented. The conclusion on the common hydrodynamic nature of the torsional oscillations and spatial-temporal variations of the poloidal flow was made. Both processes were shown to be toroidal and poloidal components of a single hydrodynamic oscillatory flow that is asymmetric about the solar equator. The basis for these processes is the physical mechanism of the loss of stability of the solar differential rotation.
