Abstract利用37个电离层垂直探测站1974-1986年的数据,采用f0F2与地磁αp指数相关分析的方法,首次得到一个太阳活动周期各年东亚—澳大利亚扇区,欧洲—非洲扇区和美洲-东太平洋扇区F2层对地磁扰动响应随地磁纬度的分布.结果指出,地磁高纬和中纬地区为负响应,低纬和赤道地区为正响应,大约在±30°附近换向.最大正响应在磁赤道附近,最大负响应在地磁纬度±50°附近,最大负响应的幅度大于最大正响应的幅度.存在明显的经度差别和南北半球不对称性.
Other AbstractUsing the data observed in 37 ionosonde stations during 1974-1986 and adopt-ing the correlation analysis method for the deviation of the daily foFz value from its monthly median to aP index,the geomagnetic latitude distribution of the FZ-layer response to geomagnetic disturbance is obtained for the first time in every year of one solar activity cycle in the East Asia-Australia sector, Europe-Africa sector and America-East Pacific Ocean sector.The results showed that the negative response appeared at the high and middle geomagnetic latitude, the positive response ap-peared at the low latitude and geomagnetic equator, the response sign changes at the geomagnetic latitude of about±300, the maximum positive response appeared at geomagnetic equator and maximum negative response appeared at the geomagnetic latitude of about±500, and the amplitude of maximum negative response is larger than the amplitude of maximum positive response.The responses have obvious longitude dependence and the asymmetry between the Southern hemisphere and the Northern hemisphere.The geomagnetic latitude distribution of the response is symmetrical between the Northern and Southern Hemispheres in the East Asia-Australia sector.But in the Europe-Africa sector and America-East Pacific Ocean sector, the asymmetry between the Northern and Southern Hemispheres is obvious,the amplitude of maximum negative response is larger in the Northern Hemispheres than in the Southern Hemispheres.
