Surface radial magnetic field Br(r = r0) and axisymmetric zonal flows 
for a dipolar dynamo model with Nρ = 1.7 a) and a multipolar one with Nρ = 2 b). The maps of Br have been low-pass filtered up to ℓmax = 10. Magnetic fields are expressed in units of the square root of the Elsasser number and velocities in units of the Rossby number.
