太阳耀斑引起的磁扰的多因子回归分析

利用多元逐步回归方法分析了太阳耀斑的日面经纬度、面积,持续时间、地球的日面纬度、地磁轴与日地连线的夹角和地磁扰动的关系。结果表明这6个因子对磁扰均有不同程度的影响,由太阳耀斑引起的地磁扰动除与耀斑的特征有关外,还受地球空间位置的影响。

The Multi-factor Regresson Analysis of the Geomagnetic Disturbances Caused by Solar Flares

The correlation between the geomagnetic disturbances caused by solar flares and the manifold factors is studied using the multi-factor successive regression analysis method. These factors include the heliographic longitude and latitude, the corrected area, and the continued time of solar flares, the earth's heliographic latitude and the angle between the orientation of the geomagnetic dipole and the sun-earth line. The results indicate the geomagnetic disturbances caused by solar flares are both affected by the characters of solar flares and the spatial locatins of the earth. The geomagnetic disturbanes is apparently affeeted by the spatial positions of the esrth in some ways.
