THE COROTATING VARIATION OF THE NORTH-SOUTH ANISOTROPY OF COSMIC RAYS
-
摘要: 本文统计分析了1971—1975年期间宇宙线北南各向异性及相关的太阳风和行星际磁场在卡林顿自转周中的变化, 即共转变化.结果表明宇宙线北南各向异性与行星际磁场分量Bx、By有非常好的相关, 相关系数高达0.8以上.利用地面观测的宇宙线各向异性有可能推求行星际磁场的极性.Abstract: Correlation analysis is made on the relation of the north-south (N-S) anisotropy of cosmic rays, observed by the Nagoya multi-directional meson telescope, with the IMFas well as the solar wind velocity within solar carrington rotation for the period 1971-1975. It is found that the N-Sanisotropy of cosmic rays correlates quite well with the Bx and By components of the IMF. The correlation coefficient mearly equals to 0.8.
