  Information - ST4.1 Theory and simulations of solar system plasmas

Event Information
Theory and simulation of solar system plasmas, from microscopic to global scale" is a session that combines presentations of original works and a few general reviews. It aims to highlight the most significant results that come from theoretical investigation and numerical simulation of the plasma dynamics in the solar system. The theoretical approach must allow to evidence the universality of the phenomena investigated, whatever the region where their role is studied, at the sun, in the solar corona, in the interplanetary space or in planetary magnetospheres. By the way, as in the last few years, the session should success in bringing together scientists who investigate similar physical processes in different parts of the heliosphere and favouring fruitful cross-fertilizing exchanges.

All possible theoretical studies concerning plasma dynamics are welcome, especially those using numerical models and simulation, since these tools are mandatory whenever analytical treatments fail, in particular when complex nonlinear and nonlocal phenomena are at work. Nevertheless, one different specific theme is put forward each year; for the 2006 session, we especially encourage all the contributions connected with the questions of “cross-scale coupling” and their modelization. This theme includes the most general problem of complexity, but also the different approaches of turbulence (strong/ weak) and all the delicate questions concerning the boundaries between modelizations, kinetic effects in fluid theories and vice-versa. Understanding the role of an exact description of the local plasma (micro- or macro-) physics in determining the non-linear states of the large global systems is one of the issues of this debate.

As in the past after the meeting a special issue of the AGU-EGS journal "Nonlinear Processes in Geophysics" will be prepared gathering appropriate contributions of this session.
