Abstract: The bifurcation behavior of a conceptual heat?salt oscillator model is analyzed by means of numerical continuation methods. A global (homoclinic) bifurcation acts as an organizing center for the dynamics of the simplified ...

Abstract: A new mechanism is proposed that explains two key features of the observed El Niño?Southern Oscillation (ENSO) phenomenon?its irregularity and decadal amplitude changes. Using a low-order ENSO model, the authors show that ...
