    "abstract": "The solar wind provides a natural laboratory for observations of MHD\nturbulence over extended temporal scales. Here, we apply a model independent\nmethod of differencing and rescaling to identify self-similarity in the\nProbability Density Functions (PDF) of fluctuations in solar wind bulk plasma\nparameters as seen by the WIND spacecraft. Whereas the fluctuations of speed v\nand IMF magnitude B are multi-fractal, we find that the fluctuations in the ion\ndensity rho, energy densities B^2 and rho v^2 as well as MHD-approximated\nPoynting flux vB^2 are mono-scaling on the timescales up to ~26 hours. The\nsingle curve, which we find to describe the fluctuations PDF of all these\nquantities up to this timescale, is non-Gaussian. We model this PDF with two\napproaches-- Fokker-Planck, for which we derive the transport coefficients and\nassociated Langevin equation, and the Castaing distribution that arises from a\nmodel for the intermittent turbulent cascade.",
