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.
