Hybrid EnKF and Particle Filter: Lagrangian DA and Parameter Estimation

Dealing with high dimensional systems is one of the central problems of data assimilation. A strategy is proposed here for systems that enjoys a skew-product structure. Christopher Jones, University of North Carolina at Chapel Hill, presents joint work with Naratip Santitssadeekorn to the Stochastic…

New averaging results motivated by climate models: fat tails, oscillations, and tipping

We review recent results where new averaging approaches are developed and applied in the context of systems with multiple time scales and fat tails and in non-autonomous multiple scale systems with oscillatory forcing. These types of systems appear in a variety of higher dimensional climate models, …

Early warning indicators for transitions in high-dimensional dynamical systems

Climate research deals with changes in the statistics rather than in the exact state of the Earth system. Ergodic theory is aimed to relating the dynamics of a system to its statistical properties and thus particularly suitable for developing a theory of climate variability. In this presentation, co…

Local and non-local mechanisms of Arctic warming

Polar amplification (PA) is a prominent feature of currently observed and predicted future climate change suggested by both observations and models. We will discuss several PA mechanisms and feedbacks in the ocean and the atmosphere suggested by different researchers and connect it to the real world…
