Cycle in solar polar activity
Abstract
Solar polar activity is dominated by small-scale magnetic elements. The most of them of dominant polarity are coincided with polar faculae. It is known that number of the polar faculae change during the solar cycle and reach their maxima at Sunspot minimum. But, the solar polar regions display the bi-polar magnetic pattern. Here, it is presented the results of the investigations of the polar magnetic elements during the solar cycle and their role in polar magnetic field reversals. The SOHO/MDI data are analyzed in form of the high-resolution synoptic maps for periods close to the maximum of B-angle for South and North poles. The dynamics of the small scale elements shows the changing of the polarity in the distribution of small scale elements during the polar magnetic field reversals.
