We present a series of 3-D MHD simulations in the anelastic approximation of active region scale magnetic flux ropes embedded in a highly stratified, turbulent model convection zone. The numerical calculations are carried out over long time scales (of order a solar rotation time) at high magnetic Reynolds numbers and suggest that the process of ``turbulent pumping'' --- the tendency for magnetic flux to be efficiently transported from surface layers to the base of the convection zone --- does not manifest itself in the absence of a convective overshoot layer. If the overshoot layer is present, we suggest a simple, statistical model (similar to a 1-D, depth-dependent eddy-diffusivity treatment with a characteristic time-scale of supergranulation) that describes the average properties of the flux storage process.
