Geophysical and man-made systems display extreme variability over wide ranges of space-time scales due to nonlinear interactions between various processes. Capturing these interactions is of vital importance in understanding the dynamics of these complex systems. They lead to extreme events ranging from floods to pandemics and climate fluctuations . They naturally call for multiple scientifically-based responses to mitigate the risks and build resilience.

This session is focused on recent progresses on nonlinear techniques (e.g., scaling, (multi-) fractals, complex networks, causality and information transfer) to uncover the underlying, non-trivial symmetries, information transfer across scales, causal effects and driving forces as well as their applications to data analysis and modelling of these complex systems and phenomena.
