Notes. Results for Boussinesq models were taken from Yadav et al. (2013a; see also Schrinner et al. 2012). Yadav et al. (2013a) distinguished between dipolar and multipolar dynamos for their Rossby number scaling, whereas we derived a single power law for both classes of dynamo models.


Dipolar models.


Multipolar models.
