Abstract

A sequence of nonlinear regimes is identified for the nonlinear development of a line-tied g mode. The dynamics of the intermediate nonlinear regime is described. This regime is operable when the mode's convection amplitude is comparable to the mode width in the direction of the density gradient. The governing equations are derived. Comparisons between these equations and direct magnetohydrodynamic simulations show agreement.
