Understanding solar wind and magnetospheric intermittent turbulence

Turbulence and Multifractals in Geophysics and Space; Brussels, Belgium, 9-11 June 2010; Space plasmas exhibit intermittent turbulent fluctuations, i.e., randomly alternating quietness and bursts. Fractals (discussed by Benot Mandelbrot in 1967) describe self-similar, irregular geometrical objects with fractional dimension. Self-similarity manifests as the recurrence of the same topology at all scales. Multifractals are a generalization of fractals and describe with geometric analogs dynamical processes whose self-similarity depends on scale. Intermittency is one possible key to understanding the energy transfer from large (magnetohydrodynamic (MHD)) scales to much smaller, kinetic scales. To review the current understanding of multifractals and intermittent turbulence in the solar wind and magnetosphere, the Belgian Institute for Space Aeronomy (BIRA-IASB) organized a workshop in Belgium.
