Multipolar decomposition of the magnetic field near the surface (with m components summed quadratically), showing the dipole,  = 1 (left), quadrupole,  = 2 (middle), and octupole,  = 3 (right), as a function of the Rossby number, Rof. At low Rof, the agreement between the simulations (purple line) and observational (dashed black line) fits is quantitatively good for all low-degree dynamo modes, with all modes showing a decreasing trend and power laws comparable to observations. The possible inverse trend for high Rossby numbers is also found in all three multipoles. Symbols have the same meanings as in Fig. 5.
