  Information - NP3.05 Uncertainty, Random Dynamical Systems and Stochastic Modeling in Geophysics

Event Information
It has long been clear that nonlinearity is at the core of geophysics, as well as the growth of uncertainty trough scales. Therefore, there is a growing recognition of a role for the inclusion of uncertainty in the modeling of complex, multi-scale and random phenomena in Geophysics.

On the one hand, broad generalizations of the deterministic dynamical approach to stochastic dynamical systems are indispensable for analyzing and simulating geophysical systems. Indeed, other
geophysical components and/or scales generally yield non-vanishing noisy perturbations, which are furthermore often colored. For instance, it has been often argued that for climate studies a red noise should be introduced to take into account the weather scales.

On the other hand, various types of stochastic modelling have been developed based on the statistical symmetries of the generating equations, in particular the scale symmetry (e.g. multifractals).

This session will be devoted to the latest theoretical developments and applications of stochastic approaches in Geophysics, as well as their confrontation in order to help the necessary blending between dynamics and stochastics to achieve a better understanding and modeling of
nonlinear phenomena in Geophysics.'
