The Nonlinear Processes in Geosciences (NP) Division is an interdisciplinary division which is concerned with all aspects on nonlinear and stochastic theories, methods and data in the geosciences. The NP division is focused on a series of nonlinear paradigms whose applications cut across the different disciplines of the geosciences (hydrosphere, atmosphere, biosphere, lithosphere, space sphere…). Examples include chaos, tipping points, nonlinear waves, similarity across scales (scaling, scale invariance, fractals, multifractals), network theory, nonlinear stochastics, predictability and its limits, pattern formation, self-organised criticality, extreme events, deep learning… The NP division welcomes mathematical and theoretical approaches, as well as applications including new methodologies, new modelling and new data analysis techniques.
Due to its interdisciplinary character, many of the NP-sessions during the EGU general assemblies are co-organized with sessions from other divisions. Potential contributors to any session are encouraged to evaluate the benefits of a multi-disciplinary organization in collaboration with the corresponding disciplinary Division.
The division is structured into several subdivisions (see the “About” tab above, for the NP Division structure information and reports).
The Division contributes to the EGU Awards & Medals programme. As for all EGU Divisions, an Early Career Scientist Award is established also for the NP Division and is given to young researchers who obtained outstanding results in the nonlinear geosciences. Every year the Lewis Fry Richardson medal is awarded to scientists for their exceptional contributions to nonlinear geosciences in general. Members of the Division are invited to contribute to the nominations (deadline are every year on the 15th June, see here) for both the NP Division Awards and Medals.
The division maintains very strong links with the EGU publication committee, and especially with the board of Editors of the open access journal Nonlinear Processes in Geophysics (NPG), an interdisciplinary journal for the publication of original research furthering knowledge on nonlinear processes in all branches of Earth, planetary, and solar system sciences.

NP Paper of the Month: “Representation learning with unconditional denoising diffusion models for dynamical systems”
About the revolution of generating butterflies Imagine the most vibrant butterfly you can conceive. Congratulations – you’ve just achieved what generative AI does! This technology can create images from simple text descriptions, revolutionising image generation. But as geoscientists, how can we use it to improve the prediction of chaotic system like our weather? How can it help us to discover properties crucial for weather prediction and climate projections? And what does it learn from data? These are the questions, we …
