佘山台地磁场太阴日变化的O_1分量

The O_1 Component of Geomagnetic Lunar Daily Variation at Sheshan

本文用Winch方法分析佘山地磁台的地磁太阴日变化的O_1分量L(O_1).首先把佘山台1960～1978年D,H和Z各分量的时均值资料作为整体分析年平均变化,然后再把资料按太阳活动性分为宁静、中等活动和活动期三组分析L(O_1)随太阳活动性的变化,并与国外一些地磁台的结果进行了对比分析。

The O1 component of geomagnetic lunar daily variation, L(O1), of the three geomagnetic elements D, H and Z at Sheshan for the period 1960- 1978 are devived by the generalized method of Winch . First the data are analysed as a whole the annual mean variations and then reanalysed after subdivision according to Solar activity to be divided into quiet, medium and activity periods. The results are tabulated, discussed and compared with other observations.
