Storage of magnetic flux tubes in a convective overshoot region

The suppression of the radial and polar escape of magnetic flux in form of toroidal flux tubes (flux rings) from low latitudes in the overshoot region below the solar convection zone through the combined action of the subadiabatic ambient stratification and the rotationally induced forces is considered. It is shown that a flux ring which is initially in thermal equilibrium with its environment and rotates with the ambient angular velocity moves radially and latitudinally towards an equilibrium configuration of lower internal temperature and larger internal rotation rate with respect to the surrounding, non-magnetic gas. Flux rings perform superposed buoyancy and inertial oscillations around their equilibrium positions
