# Alfvén 2004 Workshop

**Alfvén 2004 Workshop on Space Environment Turbulence**

*Beaulieu, France, 19-23 April 2004*

**The ALFVEN 2004 Workshop on Space Environment Turbulence, organized in the framework of the activities of WISER, the World Institute for Space Environment Research, will be held in Beaulieu, (in the French Riviera near Nice),April 19-23 2004, just before the annual EGS meeting (April, 26-30 2004).** **This meeting, which will bring together about 40 participants, is planned to be informal and to leave ample time** **for discussions. It will focus on waves, instabilities and turbulence in space plasmas, with emphasis on theory and modeling of solar wind-magnetosphere-ionosphere-atmosphere coupling, in light of recent space observations.**

**Scientific organizing committee :**

A. Chian (INPE, Sao José dos Campos-SP, Brazil)

T. Passot (Observatoire de la Côte d'Azur, Nice, France)

P.L. Sulem (Observatoire de la Côte d'Azur, Nice, France)

**Main topics to be covered:**

Coherent structures, both at large and small scales.

Wave turbulence.

Particle acceleration.

Collisionless reconnection.

Macroscopic signature of kinetic effects.

Substorm physics.
