Notes.
is the maximum of the Fourier-filtered vertical magnetic field strength at the surface (z = 0), 
is the time when 
reaches a maximum while 
is the time when 
with k∗/k1 = 2 reaches a maximum. The numbers in parentheses refer to spectral values averaged between k/k1 = 1 and 4. Regrid = urms/νkNy is the mesh Reynolds number. The column BR indicates the visual appearance of BRs at the surface.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
