... The research in this project will concentrate on the following subjects. Most importantly, motivated by periodically forced climate transitions in simple models, we shall develop the mathematical understanding of the physical paradigm of spontaneous phase transitions and stochastic resonance. To this end, subjects such as quality measures of noise tuning will be studied. A second focus is on (local) Lyapunov exponents and stochastic stability questions for non-linear systems, a topic important for predictability in reduced climate models. The underpinning of Hasselmanns stochastic reduction of climate models through scale separation has to be seen as a topic for the long run, preceded by numerical case studies of simple coupled ocean-atmosphere models.
