The Mid Pleistocene Transition from a Budyko-Sellers Type Energy Balance Model
Esther R. Widiasih, Malte Stuecker, Somyi Baek
A conceptual model of the Plio-Pleistocene glacial cycles is developed based on the Budyko-Sellers type energy balance model. The model is shown to admit a phenomenon like the Mid-…

Mixed mode oscillations of the El Niño-Southern Oscillation
Andrew Roberts, Esther Widiasih, Axel Timmermann +2
Very strong El Niño events occur sporadically every 10-20 years. The origin of this bursting behavior still remains elusive. Using a simplified 3-dimensional dynamical model of the…
