Fluctuation in polar field: Joy’s law: Tilts of bipolar sunspots increase with latitude Sources of randomness: Sources of randomness: 1. Fluctuations in the B–L process of poloidal field generation
2. Fluctuation in the meridional circulation: Direct/Observation study: (Hathaway 1996; Snodgrass and Dailey 1996; Ulrich et al. 1988; Basu & Antia 2000; Haber et al. 2002; Gonz´alez-Hern´andez, et al. 2006; Gizon & Rempel 2008) Amplitude can vary from 1 m/s to 100 m/s.
