Abstract
In this paper, we derive a new integral equation model for the Antarctic circumpolar current (ACC) by considering the radial solutions for a semi-linear elliptic equation model of gyres and applying Green’s function. We give the representation of solutions for constant vorticity and linear vorticity and show the existence and uniqueness of solutions for nonlinear vorticity. Finally, we present the Ulam–Hyers stability for the ACC involving Lipschitz-type nonlinear vorticity.
