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.
The 2023 Lewis Fry Richardson Medal is awarded to Angelo Vulpiani for contributions to stochastic resonance, as a mechanism for climate variability, the development of multifractals to describe turbulence and chaotic systems, and its implications for predictability.
The 2023 Outstanding Student and PhD candidate Presentation (OSPP) Award is awarded to Jamie Mathews How Oceans Create Extreme Temperatures
The 2023 Outstanding Student and PhD candidate Presentation (OSPP) Award is awarded to Lucas Schmutz A multivariate approach to combine general circulation models using graph cuts
The 2022 Lewis Fry Richardson Medal is awarded to Ulrike Feudel for fundamental contributions on tipping points in multistable systems.
The 2022 Division Outstanding Early Career Scientist Award is awarded to Tommaso Alberti for outstanding research in the fields of data analysis and modeling, via dynamical system approaches, to understand complexity in geoscience, space plasma, and the planetary environment.
The 2022 Outstanding Student and PhD candidate Presentation (OSPP) Award is awarded to Benedikt Schulz Machine learning for postprocessing ensemble forecasts of wind gusts with a focus on European winter storms
The 2022 Outstanding Student and PhD candidate Presentation (OSPP) Award is awarded to Lana Blaschke AMOC early warning signals in CMIP6 models?
Scientists find that faster warming in the Arctic will lead to a global 2 degree Celsius rise being reached eight years earlier than if the region was warming at the average global rate. And Geodesy researcher Andreas Kvas explains how Earth’s geometric shape, orientation in space, and gravity field are affected by climate-relevant processes.
This month, EGU observed International Day for Biosphere Reserves, while also diving deep into monster lore to mark 90 years since the first fake photo of the Loch Ness Monster.
