Solar polar magnetic field

摘要: The solar polar magnetic field has attracted the attention of researchers since reversal was revealed in middle last century (Babcock and Livingston, 1958). regularly reversed because flux is transported from sunspot formation zone owing to differential rotation, meridional circulation, turbulent diffusion. However, modeling these processes leads ambiguous conclusions, as a result which it sometimes unclear whether transport model actual. Thus, according Hinode data, problem standard (Shiota et al., 2012) consists that decrease Southern Hemisphere lags behind such Northern (from 2008 June 2012). On other hand, Svalgaard Kamide (2012) consider asymmetry sign simply results emerging region. A detailed study evolution Solar Dynamics Observatory (SDO) data for May 2010–December 2012 illustrated present work. Helioseismic & Magnetic Imager (HMI) form component along line sight (the time resolution 720 s) are used here. fluxes regions at high latitudes have been compared.
