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!

NP division president

Current issue of the EGU newsletter

Thank you to everyone who submitted an abstract to the EGU 2017 General Assembly! With over 17,500 abstracts received, and an improved set up to accommodate the high number of expected participants, the conference promises to be the largest and most exciting to date. We look forward to welcoming everyone in Vienna on 23-28 April!

We would also like to draw your attention to a couple of deadlines we have coming up. The first regards a job opportunity at the EGU Executive Office: if you'd like to help us bridge the gap between science and policymaking, consider applying for our vacancy by 5 February. Until 15 February you can also apply to receive one of EGU's Public Engagement Grants to develop a project that aims to raise awareness of geosciences outside the scientific community. For the chance to win a free registration to next year's General Assembly, consider applying to the Communicate Your Science Video Competition (by 26 February, for early career scientists) or to the EGU Photo Competition (by 1 March).

Last but not the least, if you'd like to organise an EGU Galileo Conference, a meeting addressing a well-focused, cutting-edge topic at the frontier of geosciences research, make sure to apply for funding by 28 February. For those interested in helping further the EGU education programme, apply to be part of the EGU Committee on Education.
