- Аннотация: An advanced theory of the solar wind interaction with the Earth’s magnetosphere and magnetospheric boundary layers formation requires the consideration of the existence of high level of turbulence in the magnetosheath. Therefore, it is of great interest to compare the magnetic field parameters just in front of the magnetopause with the interplanetary magnetic field. We analyze the dependence of the magnitude of the magnetic field, its three components,and the clock angle in the magnetosheath just in front of the magnetopause on the same values in the solar wind before a bow shock using data of the THEMIS mission. The present study compares the magnetic field parameters near the magnetopause, measured for 3 s (spin resolution of the THEMIS satellites), 30 s (the characteristic correlation time according to certain estimates), and 90 s (the threefold longer interval than the characteristic correlation time). The aim of this study is to determine the average dependences of the magnetic field parameters at the magnetopause on the corresponding parameters in the SW for the selected averaging times. The time delay of the solar wind arrival at the subsolar point of the magnetopause was taken into account. We selected events for which the direction of the magnetic field at the magnetopause is highly different from the direction of the magnetic field in the solar wind up to the sign change.
