  "abstract": "In this work, our primary goal is to study the Poincare map and the existence of limit cycles for Welander's model that describes ocean convection. Welander developed two versions of his model, one with a smooth transition between convective states, and one with an abrupt non-smooth change. Our focus in this paper is to study the non-smooth model. Approaching through the Poincare Map, we demonstrate analytically the bifurcation of a stable limit cycle surrounding an escaping segment.",
