Abstract
In this paper, we study the nonlinear stability of one-layer geostroph ic fronts described by frontal geostrophic equations, We show that the beta-effect plays a crucial role in the stability of one-layer geostr ophic fronts. Especially, we prove that the class of nonlinearly stabl e fronts is more restricted when the beta-effect is present than when it is absent.
