Stochastic fluctuations of the solar dynamo
Abstract
The solar dynamo equations are presently solved in a slab with a single mode, taking the alpha-coefficient to be constant in space, but fluctuating stochastically in time with given amplitude and correlation time. Choudhuri's (1990) contention that the solar dynamo is of the alpha-squared(omega) type is reinforced by the solar behavior's qualitative agreement with such a dynamo's level of irregularities, which increase with rising amplitude or correlation time of stochastic fluctuations.
