Abstract	The penetration and transformation of solar-wind plasma structures at propagation through the turbulent magnetosheath were studied over time intervals from a few seconds to a few minutes using data of plasma density measurements on two closely located satellites of the Themis mission. It was shown that near Earth bow shock and the magnetosheath have added high-frequency fluctuations with frequencies higher than 0.01–0.02 Hz to initial variations of solar wind’s plasma density. As a result of the analysis of several long intervals, it was found that the correlation coefficient can undergo drastic changes, while decreasing from large to rather small values for several minutes and then increasing again. Factors affecting the level of correlation between the solar wind’s plasma density and the magnetosheath were studied statistically. It was shown that a high level of correlation is observed, in a large percentage of cases, at high values of the interplanetary magnetic field magnitude, the plasma density and the magnitude of solar wind’s directed velocity. The level of correlation also considerably grows with increasing amplitude of solar-wind plasma structures.
