Solar-Wind Structure and the Kolmogorov Spectrum



Joe Borovsky (Los Alamost National Laboratory)

Strong discontinuities can dominate the spectral power of the solar wind and the Kolmogorov f-5/3 power-law spectrum can be produced from a time series of strong discontinuities extracted from solar-wind measurements. Strong discontinuities represent structure in the solar-wind plasma, not turbulence. Using measurements from the ACE spacecraft and using numerical experiments, the connection between the properties of the solar-wind plasma and the Kolmogorov f-5/3 spectrum is explored.
