MULTIPERIODIC OSCILLATIONS OF THE SOLAR M AGNETIC ACTIVITY AND THEIR POSSIBLE CONNECTION TO HYDRODYNAMIC OSCILLATIONS

A hypothesis is critically analyzed, according to which the observed s ystem of the solar magnetic activity periods is caused by the influenc e of rotating hydrodynamic structures upon the magnetic field localize d at the bottom of the solar convection zone. The location and possibi lity of interaction are investigated for two types of such structures, related to r- and g-modes of the solar oscillations. It is shown that only g-modes can efficiently influence the deep-laying magnetic field s, whereas the interaction of r-modes, localized in the upper part of the convection zone, with these magnetic fields, as well as with the g -modes, must be significantly weaker.
