Abstract

Global rotation inversions can probe the pattern of zonal flows well into the convection zone. In this paper, we test the ability of the inversions to constrain the predictions of dynamo models. A flux-transport dynamo model, including a mean-field theory of differential rotation and allowing for a feedback of the Lorentz force on differential rotation and meridional flow, was used to produce a 22-year cycle of simulated rotation profiles. These were then subjected to simulated inversions with realistic mode sets and errors, in order to test how well the subtle subsurface features of the input profile could be recovered. The preliminary results are quite encouraging.
