Modification of small- and middle-scale solar wind structures by the bow shock and magnetosheath: Correlation analysis
Original language description
The paper is devoted to a modification of small- and middle-scale solar wind plasma and magnetic structures during their propagation through the bow shock and magnetosheath. We use data from two closely spaced THEMIS spacecraft in the solar wind and magnetosheath and we concentrate on the slow solar wind and quasiperpendicular bow shocks. We determine a cross-correlation function between time series of the solar wind and magnetosheath ion densities and magnetic field magnitudes. The correlation coefficient is calculated for data smoothed on different subintervals from 10 to 170 s and we show that the correlation coefficient between both quantities strongly depends on the duration of smoothing subintervals in the range of 10-50 s, whereas it is not significantly affected if the duration of the subintervals exceeds 50-100 s. It means that the fluctuations with frequencies below 0.01-0.02 Hz are of the solar wind origin, whereas bow shock and magnetosheath processes contribute to the enha
