Stochasticity, Multiplicity of Scales, Memory and Thermodynamics in Geophysics

AGU Fall meeting - San Francisco 5-9 December 2011

Submission deadline : Thursday 4 August 23:59 EDT/03:59 +1 GMT.

NG15 session : Stochasticity, Multiplicity of Scales, Memory and Thermodynamics in Geophysics

Sponsor : Nonlinear Geophysics (NG) ; co-sponsors : Atmospheric Sciences (A), Earth and Planetary Surface Processes (EP), Global Environmental Change (GC), Hydrology (H), Ocean Sciences (OS), Seismology (S), Tectonophysics (T)

Description :

The following five main themes will be at the core of this session :

• (i) the fundamental understanding of the interplay between stochastic and deterministic aspects of multiscale geophysical phenomena,
• (ii) the role of memory effects,
• (iii) the knowledge gained from multiscale observations and simulations,
• (iv) the generic processes of multi-scale interactions,
• (v) the fundamental statistical mechanical and thermodynamical properties which can help to unravel the complexity of the analyzed geophysical systems.

Invited speakers :

• David Battisti (U. Washington),
• Olivier Pauluis (Courant Insittute, New York),
• Philip Sura (NOAA, Boulder),
• Paul D. Williams (U. Reading)

Conveners :

• Mickael Chekroun (UCLA),
• Valerio Lucarini (U. Reading),
• Daniel Schertzer (U. Paris-Est)

NG11 session : Scaling and Fractals After Mandelbrot : On the Frontiers of the Geosciences

Sponsor : Nonlinear Geophysics (NG) ; co-sponsors : Atmospheric Sciences (A), Biogeosciences (B), Global Environmental Change (GC), Hydrology (H), Natural Hazards (NH), Ocean Sciences (OS), Seismology (S), SPA-Magnetospheric Physics ( SM), Tectonophysics (T), Volcanology, Geochemistry and Petrology (V))

Description :

Scaling and fractals are key components of the nonlinear revolution that began in the 1970’s with Mandelbrot’s pioneering work. Since then, both theoretical scaling tools and practical data analysis techniques have greatly evolved and today applications cover virtually all the geosciences. However, there is a continuing need to compare new scaling techniques, formalisms, applications in order to keep pace with continuing developments. We call for papers that build on these advances, both theoretical and practical : fractals, multifractals ; self-similarity, self-affinity ; modelling and analyses, including extremes.

Invited speakers :
