Abstract以IPS观测数据为基础,在考虑了加速剖面对太阳风源位置和速度大小的影响下,探讨了1984年1745-1755Carrington周太阳风速度在源表面上的二维分布,结果显示:观测和理论结果均显示出此期间北半球太阳风速度明显高于南半球,特别是经度0-30°,300-360°N的高速流均有不同程度的从极区向南侵的现象,低速带一磁中性线有一定程度的类似即均为单峰结构.但理论和观测给出的峰值位置与磁中性线的
Other AbstractThe solar wind speed structure on the source surface is studied on the basis of IPS data in the year of 1984 during Carrington rotation 1745-1755.IN the mapping-back processes,the influence of acceleration on the foot point of the Archimedian spiral and the values of solar wind speed are considered.The results is compared with the map determined by the MHD model which uses the K-coronal brightness and photospheric magnetic field as inputing condition. This results are also compared with that from the other authors.The comparison shows that:the MHD model can preliminarily work out the 2-D structure of solar wind;and the decrescent amplitude and width of the low-speed belt seems to imply the existence of a latitudinal direction stream.
