Description

There is still a missing link in dynamo models between generating strong toroidal fields at the bottom of the convection zone and the sunspots as measures of activity. Since rotation is an important factor in the rise of magnetic flux through convection zones, we study the flux emergence under the influence of different rotation profiles. It is difficult to simulate realistic convection, its generation of realistic differential rotation, and the rise of magnetic flux in a single simulation. Therefore, we choose to enforce various differential-rotation profiles in highly stratified, compressible simulations and study - in a first step - their influence on the emergence latitudes.
