Division on Nonlinear Processes in Geosciences (NP)

President: Stéphane Vannitsem,
Deputy President: François Schmitt,

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 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 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!

In early and mid-September, strong earthquakes hit Mexico causing widespread damage and casualties. On the EGU blog, GeoLog, we rounded up the available scientific information on the earthquakes, including commentary by EGU seismologists. Meanwhile, in Bali, Indonesia, authorities have evacuated areas around Agung Volcano, leading to the displacement of over 75,000 people. On the new Geochemistry, Mineralogy, Petrology & Volcanology blog, GMPV Division President Mike Burton writes about the ongoing threat of an eruption at Agung.

This week, with the deadline for session proposals now closed, the EGU Programme Committee is meeting to finalise the session programme for the EGU 2018 General Assembly. Very soon, you’ll be able to start submitting abstracts to the meeting. If you’d like to apply for funding to attend the General Assembly, beware that you’ll have to submit your abstract by 1 December. If you know a school teacher interested in learning more about Earth sciences directly from researchers, make sure to let them know about the next Geosciences Information For Teachers workshop, taking place at the EGU 2018 General Assembly.
