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

In just a couple of days, the meeting programme for the EGU 2017 General Assembly (23–28 April, Vienna) will be published online. If you have an abstract accepted to the meeting, you should receive your letter of schedule soon, too. Before then, make sure you enter the EGU Photo Competition (deadline 1 March) for a chance to win a free registration to next year's General Assembly.

For the first time, the EGU is offering a mentoring programme for novice conference attendees at its annual General Assembly to connect them with more experienced participants. The programme promises to be a rewarding experience for both mentees and mentors, so do consider signing up if you are either an early career scientist (ECS) or would like to mentor first timers!

For those interested in helping further the EGU outreach and ECS programmes, apply to be an ECS representative or be part of the EGU Outreach Committee. 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, this is your last chance to apply for funding from the EGU (deadline 28 February).
