Other AbstractThe solar wind dynamic pressure pulses(DPPs) are a kind of important interplanetary small-scale disturbance structure. When it interacts with the magnetosphere,it will cause global strong disturbances in the magnetosphere-ionosphere coupling system that affect almost all major plasma regions and current systems in the magnetosphere and ionosphere.In this paper, the recent progress in the studies on the responses of the magnetosphere in multiple spatial and temporal scale to the solar wind dynamic pressure pulses is summarized , focused on the obser - vat ions and the physical models . In addition , we report the new observations of TC-1 , when the spacecraft is located in the near-Earth magnetotall plasma sheet , that the interplanetary shock directly drives the enhanccmcnts of the plasma oscillations in the magnetotail plasma sheet . The shocks are observed by WIND on November 07 , 2004 . Prior to and after the shock , the IMF is either weakly southward or northward . The responses of the plasma sheet to the two shocks are intense and much similar . When the shock interacts with the magnetosphere , the magnetic field impulsively increases 12 min after the gcomagnetic field sudden impulse (SI ) judged from the Sym-H index change , and the magnetic field line is stretched . on the other hand , all of the ion density , the ion temperature , and the velocity of ion flow in the plasma sheet increase . Interestingly , quasi-periodical oscillations of the ion flow are suddenly enhanced , and the plasma flow is basically perpendicular to the local magnetic field . The responses of the magnetic field and the plasma are nearlys simultaneous . The responses in the plasma sheet are probably caused by the lateral compression due to the dynamic pressure enhancement downstream the shock when the shock propagates antisunward in the magnetosheath .
