摘要：
Previous observations have shown that the solar wind is decelerated and deflected in the earth's upstream region populated by long-period waves /1-3/. This deceleration is correlated with the 'diffuse' but not with the 'reflected' ion population. The speed of the solar wind may decrease tens of km/s in the foreshock region. The solar wind dynamic pressure exerted on the magnetopause may vary due to the fluctuation of the solar wind speed and density in the foreshock region. In this study, we examine this solar wind deceleration and determine how the solar wind deceleration varies in the foreshock region.
