A DYNAMO WAVE IN A THIN SHELL

The properties of a dyn,uno wave generated in the solar convective zon e by the alpha omega dynamo mechanism are investigated. The analysis i s based on a Parker dynamo wave model, taking account of the thickness of the solar convective envelope. A nonlinear ao dynamo with various helicity suppression regimes is considered. An asymptotic solution of the nonlinear dynamo equations is constructed in the approximation of large dynamo number (\D\ much greater than 1). Similar solutions are o btained for different types of helicity suppression.
