Top panel: latitudinal migration of the toroidal magnetic field obtained for the Sun. The plot shows the result of the integration of the one-dimensional dynamo model with a constant radial rotation profile in the generation region as main ingredient. Contours correspond to the maximum value of the B-field, and 4/5, 3/5, 2/5 and 1/5 of that value. Bottom panel: magnetic wave obtained as the averaged un-signed magnetic field at all latitudes.
