Scaling and a Fokker-Planck Approach to Fluctuations in the Solar Wind Plasma

by Dr. Bogdan Hnat
University of Warwick

Abstract

Statistical properties of the solar wind fluctuations emerge as a simplifying aspect of their dynamics. In particular, scaling found in these fluctuations can constrain existing models of their origin and evolution. We use model independent scaling analysis to address following issues:
  • passive versus active dynamics of the density and the magnetic field magnitude
  • estimates of intermittence-free scaling exponents with implications to various turbulence models
  • stochastic modeling of the probability density function dynamics
    • as a function of temporal scales based on the Fokker-Planck equation
