Fig. 10

Decomposition of numerical dynamo simulation only using coefficients that are larger than the input value. Flow maps of the decomposition shown in Fig. 7 when only the absolute value of each coefficients that are bigger than the input coefficients is plotted. There is no longer a distinction between inside and outside the region of interest, and the flow is concentrated in strong bands along the boundaries of the regions. The \(\phi\)-component of the toroidal flow is shown
