Division on Nonlinear Processes in Geosciences (NP)

President: Shaun Lovejoy,
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.


New NP executives

As incoming NP president at the April General Assembly, I would like to warmily thank Henk Dijkstra my predecessor for the last four years; the following summary  (since July 2012) mostly concerns achievements under his mandate.

First, I’de like to introduce the new NP executive (some of the faces are old and some are new): 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), Vincent Rey (NP7, Nonlinear Waves), Valerio Lucarini (NP8, Nonlinear Stochastics), Daniel Schertzer (publications), Shaun Lovejoy (Programme group chair), Isabel de Lima (Scientific Affairs), August Gires (Webmaster).  The new Richardson medal committee is composed of: Chair: C. Nicolis, Members: H. Swinney, J. Kurths, S. Fauve, K. Fraedrich.

Thanks to all you efforts, the 2013 General Assembly featured 377 NP abstracts in 18 NP sessions and 11 session co-organized with other divisions.  In addition, three NP short courses were organized:

1. Nonlinear time series analysis: R. Donner, S. Barbosa.

2. Tipping Points in the Geosciences: M. Ghil, P. Ditlevsen, H.A. Dijkstra.

3. Predictability in Theory and Predictability in Practice: L. Smith.

I should also mention the following NP honours:  Outstanding Student Poster Award 2012: Auguste Gires, Outstanding Young Scientist Award 2013: Yongxiang Huang, Lewis Fry Richardson Medal 2013: Juergen Kurths.

Thank you for all your efforts; I’m looking forward to seeing you all in Vienna in 2014!

-Shaun Lovejoy,

NP division president

Current issue of the EGU newsletter

EGU newsletter cover image

This month saw the publication of the EGU 2017 General Assembly programme, which includes about 1000 sessions and over 17,500 abstracts. The conference is less than a month away, and promises to be the largest and most exciting to date. To attend, don’t forget to register online, or on-site during the week of the meeting (23–28 April).

In other news, this month the EGU has announced that it is supporting March for Science. This global movement will culminate with a march on Earth Day, April 22, 2017, in Washington DC, as well as in many cities around the world, including Vienna. EGU President Hans Thybo said: “While the March for Science idea started in the US, its mission and objectives are global and nonpartisan. A movement that champions science, supports freedom to conduct responsible scientific research, and calls for more evidence-based policy, is one that aligns with EGU’s own objectives.”
