Kinematic Dynamo Model of a Solar Magnetic Cycle

The paper deals with the problem of explaining origin and nature space-time variations in magnetic activity Sun. It presents a new hydrodynamic model solar cycle, which uses helioseismological data on differential rotation convective zone. is based hypothesis emergence global flows as result loss stability differentially rotating plasma layer First, are calculated without accounting for effect field them. Under this condition, it shown that solutions found describe all observed surface Sun: permanent meridional circulation from equator to poles, torsional oscillations flow. We conclude last two azimuthal components single three-dimensional Second, simulate dynamics field, velocities migrating spatial profile angular velocity internal zone obtained helioseismic measurements were used. Good coincidences have been between characteristics variable fields generated by them values surface. An explanation given some phenomena Sun, could not be explained within framework available models.
