A Physical Mechanism for the Prediction of the Sunspot Number During Solar Cycle 21.
Abstract
On physical grounds it is suggested that the sun's polar field strength near a solar minimum is closely related to the following cycle's solar activity. Four methods of estimating the sun's polar magnetic field strength near solar minimum are employed to provide an estimate of cycle 21's yearly mean sunspot number at solar maximum of 140 + or - 20. This estimates is a first order attempt to predict the cycle's activity using one parameter of physical importance.
