摘要:	研究期間：10108~10207;The coronal hole is the main source of high-speed solar wind. The high-speed solar wind can have a drastic impact on the Earth’s electromagnetic environment. To understand the relationship between the coronal hole and the high-speed solar wind, the STEREO (Solar TErrestrial RElations Observatory) and SOHO (SOlar and Heliosoheric Observatory) data in difference view angle will be used to monitor the characteristics of coronal hole and compare them with in situ solar wind observations at 1 AU. With multiple observations, we can retrieve information about how the solar wind speed at 1 AU varies with the development of the coronal hole in a time scale of a few days. Past studies used single observations; however, in this study we will use the multiple observations from STEREO and SOHO to investigate the evolution of coronal holes and their relationship with the variations in the plasma parameters of the solar wind.
