# Turbulence - From Basics to Geodynamics

**February 9.-10. 2009, Münster**

The attempt to understand complex systems, often summarized under the topic nonlinear science, is one of the biggest and most interesting challanges of modern Science. One famous example from this class of problems is the turbulent motion of fluids and gases. Turbulence often served as paradigm for complexity. During the last century the theory of nonlinear dynamical systems was strongly influenced by turbulence research and vice versa. Additionally its relevance for engineering applications and scientific fields ranging from geophysics to astrophysics makes this phenomeneon between chaos and self organization an interesting subject of scientific research.

The goal of the workshop is to bring together people from basic turbulence research and the geophysical field to see to which extend turbulence is relevant for geophysical systems and which results from basic research are important for the understanding of phenomenons like the geodynamo.
