| Abstract: |
Previous work on the angular momentum balance and meridional circulation of the solar convective zone (SCZ) generally consists either of semi-analytic approaches in which a simple turbulence model is adopted, or full direct numerical simulation (DNS) of the hydrodynamics or magnetohydrodynamics (MHD). In both instances the inclusion of magnetic fields has been troublesome. Also, both approaches have had difficulty reproducing the known angular velocity profile of the SCZ; this is the Taylor Number Puzzle. I discuss preliminary work in which I incorporate magnetic fields into a viscoelastic turbulence model for the SCZ and apply this to the problem of meridional circulation and angular momentum balance. The principle idea is that turbulent magnetic fields act like long polymers and give the plasma elastic properties. I suggest that such an approach may help solve the Taylor Number Puzzle of the SCZ and bring theoretical predictions for the large-scale motion of the SCZ in line with observations. |
