  1. Dynamo models time-average and standard deviation values. St/Ad is stretching/advection RMS ratio, and \({\mathcal {P}}/{\mathcal {T}}\) is poloidal/toroidal flow RMS ratio. \(H_u\) is the helical flow correlation (13), \({\text {corr}}(|B_r|,\delta _h^-)\) and \({\text {corr}}(|B_r|,\delta _h^+)\) are the correlations between the absolute radial magnetic field and downwelling (14) and upwelling (15), respectively. Also, the number of analyzed magnetic flux patches of each type is given: high-latitude normal intense flux patches (HN), low-latitude normal intense flux patches (LN) and low-latitude reversed flux patches (LR)
