| Abstract: |
We examined the distribution and concentration of the solar magnetic fields from the Wilcox observatory synoptic charts for the whole period of their existence (May 1976 – February 2006). We divided them into four latitudinal zones, studying the changes of their various structures, density, etc. These sets of maps demonstrate striking regularities in the photospheric magnetic field distribution with time, continuous existence of characteristic longitudes of magnetic field concentration and their longitudinal shift with three main rotational periods of 26.8, 28.2, and 27.14 days. They show formation of specific structures of background weaker fields, connected with the development of activity complexes, polarity alternation, etc. We mention the possible sources of found regularities in the solar activity modulation. |
