摘    要:本文根据1961—1971年我国五个地磁台北向强度的资料,采用长期变化二次项的残差ΔX,讨论了我国境内太阳活动周期的地磁效应。结果表明,各台ΔX的变化与太阳黑子数平均为11年周期有关,其相关系数平均为-0.77;ΔX的变幅随纬度的增高而有所

关 键 词:太阳周期   地磁效应   太阳活动周期   地磁场   太阳黑子数   地磁台   位相滞后   相关图   长期变化   变幅

Abstract:This paper discusses the magnetic effect of solar active cycle within Chinese territory. The data,consist of the measurements of geomagnetic north components from five geomagnetic stations during 1961-1971,and the residual error(ΔX) of quadratic expressions of secular variation are used. The results show that the variations of ΔX in each station are correlated with the sunspot numbers with period of about 11 years.The correlation coefficient was -0.77; the amplitude decreased with the latitude and the phase fall behind one year. These seem to characterize the effect of magnetic ring current of solar active cycle on the area of medium and low latitudes.
