Nonlinear Geophysics Focus Group

Welcome to the Nonlinear Geophysics Focus Group

This focus group was formed in 1998 to meet a growing interest in the analysis and modeling of nonlinear behavior in geophysical processes. The group focuses on quantifying nonlinear behavior through analysis of geophysical data and modeling using the mathematical tools and approaches of fractals, chaos, scaling, critical phenomenon, nucleation, cellular automata, and self-organizing and complex systems. Why do we need such nonlinear approaches? Quantification of nonlinear behavior and sensitivity to initial conditions are essential for forecasting the temporal and spatial behavior of many earth processes. Members of this group have made major contributions to understanding how earth processes scale and evolve in space and time including: earthquakes, climate, particle dynamics in the solar wind, dynamics of solar processes, landform dynamics, ecological dynamics, and nonlinear data inversion techniques. This focus group is trans-disciplinary and has affiliates from each of the AGU sections. If you are interested in the nonlinear aspects of the system you study, we invite you to affiliate with us.
