| Session Description | Nonlinearity is considered the origin of many properties of complex systems in nature, such as the systems encountered in geosciences. These properties include chaotic behaviour or sensitivity to initial conditions, emergence of patterns (some of which through self-organization), phase change or regime shift, and multiscale interaction, among others. The studies on nonlinearity and the associated problems in geosciences can be generalized as dynamical systems approaches, with consideration of both deterministic and stochastic dynamical systems. These studies include theoretical development and/or applications of theories, such as chaos, (multi) fractals, self-organized criticality, and complex networks to atmospheric, oceanic, hydrological, and other systems. The time span of the phenomenon under study may range from a few minutes (e.g., covering a flash flood event) to centuries (e.g., covering long-term climate change). This session is intended to cover research on all aspects of nonlinearity and related properties of complex systems encountered in geosciences, including the following topics: (1) Scales and scaling analysis, analysis/development of simple low-dimensional models and/or large-scale dynamic models for the atmosphere, oceans, and hydrology; (2) Predictability and evaluation studies of these models based on nonlinear methods; and (3) Modeling the connections and interactions between the different geophysical systems. We welcome abstracts in these topics and related ones. The main aim of this session is to stimulate the research community in this emerging area within the Asia-Oceania region, and to facilitate networking activities to advance research in this area. |
