Linear fits of polarity migration paths for the different regions of the solar poles indicated in Fig. 13. Each panel shows the absolute latitude of magnetic polarity inversions (zero-crossings) as a function of time. The time is calculated in days from the start of each migration at ±50°. Red lines represent linear regression fits, with the corresponding meridional flow velocities and r² values indicated. Panels a–d show north pole migrations, while panels e and f show south pole migrations. Gray circles indicate outliers excluded from the fits.
