Division on Nonlinear Processes in Geosciences

President: Stéphane Vannitsem (np@egu.eu)
Deputy President: François Schmitt (francois.schmitt@univ-lille1.fr)

Although the geosciences are rife with nonlinearity, the NP division is focused on a series of nonlinear paradigms whose applications cut across the “geospheres”, disciplines.  Examples include deterministic chaos, tipping points, nonlinear waves, similarity across scales (scaling, scale invariance, fractals, multifractals), network theory, stochasticity, predictability and its limits, pattern formation, self-organized criticality, extreme events.  NP geoscience is highly multidisciplinary, it plays an important role in fundamental geoscience.  Applications of NP science include new methodologies, new modelling and new data analysis techniques.

NP division at the EGU General Assembly 2018

Dear Colleagues,

The NP division activities at the EGU 2018 were a real success with more than 500 abstracts, 5 short courses, and two interdisciplinary-transdisciplinary session and a townhall. 10 sessions were also co-organized with other divisions (about 300 abstracts). I would like to thank all the conveners and participants for this success.
NP honours have been awarded to Tim Palmer with the Lewis Fry Richardson Medal 2018, and to Davide Faranda with the Outstanding Early Career Scientist Award 2018.

The preparation of the next assembly will start soon (and can be followed at http://www.egu2019.eu) and in this context I would like to remind you that proposals for the NP awards (Lewis Fry Richardson Medal and the Outstanding Young Scientist Awards) should be introduced before June 15, 2018. The link associated to these awards is https://www.egu.eu/awards-medals/.

Thank you for all your efforts!

Looking forward to seeing you all in Vienna in 2019!

NP division at the EGU General Assembly 2017

First I would like to warmly thank Shaun Lovejoy my predecessor for the last four years during which he promoted new activities within the NP division in particular the short courses, and enhanced collaborations at the level of the Union.
The new NP executive board is now composed of Stefano Pierini (NP2, Dynamical Systems Approaches to Problems in the Geosciences), François Schmitt (NP3, Scales, Scaling and Nonlinear Variability), Reik Donner (NP4, Time Series and Patterns), Olivier Talagrand (NP5, Predictability), Jose Redondo (NP6, Turbulence, Transport and Diffusion), Philippe Fraunié (NP7, Nonlinear Waves), Valerio Lucarini (NP8, Nonlinear Stochastics), Daniel Schertzer (publications), Stéphane Vannitsem (Programme group chair), Davide Faranda (Scientific Affairs), Igor  da Silva Rocha Paz (Early Career Scientists), Shaun Lovejoy (Division Affairs) August Gires (Webmaster).  The new Richardson medal committee is composed of: Chair: Annick Pouquet, Members: Edward Ott, Peter Read, Daniel Schertzer, Olivier Talagrand, Tamas Tel.

The EGU General Assembly 2017 was a real success in terms of number of participants and activities. The NP division contributed to this success with 372 abstracts within 14 sessions, 9 short courses, and one interdisciplinary session and two sessions in the Great Debates organized at the level of the Union. 7 sessions were also co-organized with other divisions (170 abstracts). I would like to thank all the conveners and participants for this success.
NP honours have been awarded to Edward Ott with the Lewis Fry Richardson Medal 2017, and to Malte Stuecker with the Outstanding Student Poster and Pico Award 2016.
The preparation of the next assembly will start soon (and can be followed at http://www.egu2018.eu) and in this context I would like to remind you that proposals for the NP awards (Lewis Fry Richardson Medal and the Outstanding Young Scientist Awards) should be introduced before June 15, 2017.

Thank you for all your efforts!
Looking forward to seeing you all in Vienna in 2018!

Current issue of the EGU newsletter

Last week, the EGU hosted its first science-policy dinner debate in Brussels. The event, 'Horizon Geoscience: overcoming societal challenges, creating change', was organised in collaboration with the European Federation of Geologists (EFG) and brought together geoscientists, policymakers and industry representatives. On the EGU website, we report on the outcome of the discussion and publish the key findings from the Horizon 2020 Geoscience Survey conducted earlier this year.

In the past few weeks, we have also issued three press releases highlighting research published in some of EGU's open access journals. Follow the links to find out how bombing raids in the Second World War impacted the ionosphere, how glacial geoengineering could help limit sea-level rise, and what the point of no return for climate action might be.
