Scientific paper

Analytical calculations and numerical results are presented for slender buoyant magnetic flux tubes moving through the solar convective envelope. Conservation of mass and magnetic flux is assumed together with thermal equilibrium with the surrounding gas. Two braking mechanisms are investigated: aerodynamic drag and viscous forces. The resulting vertical velocities are always of the order of a few meters per second, causing timescales of the order of the solar cycle for ascension through the whole convection zone. Thus there is enough time for the fields to be amplified by differential rotation and the alpha effect in order to build up an alpha-omega dynamo.
