Torsional waves on the Sun and the activity cycle

Abstract

Some properties of the recently-discovered torsional oscillations of the Sun are presented. The detailed relation of this velocity feature to magnetic activity gives evidence that these motions represent a fundamental oscillation within the Sun that is responsible for the solar activity cycle and that they are not a natural consequence of an α-ω dynamo. A new torsional oscillation with wave number 1 hemisphere−1 is demonstrated to exist on the Sun.
