ABSTRACT=Varying solar wind plays a crucial role in the processes inside the magnetosphere. Statistical studies generally reveal the geoeffectiveness of solar wind streams of different origins and types characterized by various parameters such as dynamic pressure, magnetic field orientation etc. However, still the predictions of the space weather are not completely reliable. Small-scale structures (observed as high-amplitude variations with frequencies above 0.01 Hz) involved to the turbulent flow in the solar wind and in the magnetosheath, may contribute to the models’ inaccuracies. Spacecraft measurements obtained during last two decades gave a great amount of new information about small-scale plasma processes in the near-Earth space. However, influence of the solar wind on the dynamics of the small-scale structures in the magnetosheath was addressed rarely. Present review summarizes experimental studies this influence including features of turbulence around ion scales. The study aims to give a general picture of the problem and underline the gaps in current understanding of the role of the dynamics of the small-scale structures and turbulence in the solar-terrestrial relations.
