Abstract
The ENSO model by Timmerman and Jin (2002) models the El Niño-Southern Oscillation using 3 prognostic differential equations. In this thesis, we use one of the trajectories of this ENSO model and consider a Poincaré section given by the local maxima of eastern Pacific sea surface temperatures. The relation of the resulting sequence of values can be approximated with 1 dimensional maps, with which we will examine bifurcations, snap-back repellers and predictability of extreme events. Lastly, we conclude that employing a toy model can be useful since it reduces, for example, time and calculation capacity while we still obtain similar results for the chosen variable.
