| 摘 要： | 利用第4代地磁场综合模型CM4, 研究了中国大陆地区1960--2000年磁静日期间地磁外源场的变化情况, 并进一步计算分析了外源场中的电离层场及磁层场的分布与变化.结果显示, 北向分量X的外源场强度在40年间呈先增加后减小的趋势, 共减少了约32 nT, 其磁层场强度呈先增大, 然后逐年减小的趋势, 共减少了约23.7 nT; 东向分量Y的外源场强度呈先减少后增加再减少的趋势, 共增加了约3.8 nT, 其磁层场强度呈先减小, 再逐年增加的趋势, 共增加了约2.3 nT; 垂直分量Z的外源场强度呈先减少后增加的趋势, 共增加了约4.6 nT, 其磁层场强度呈先减小后增加的趋势, 共增加了约9.3 nT. 三分量的电离层场强度变化均小于1 nT, 其分布在1960--1970和1970--1980年, 1980--1990和1990--2000年呈现正负互相变换的现象, 该现象可能与太阳11年活动周期有关.

| Abstract: | The fourth generation comprehensive model of magnetic field CM4 was reasonably used in this paper to study the variation of external field in magnetic quiet periods over Chinese mainland during 1960-2000.The distribution and variation of ionospheric field and magnetospheric field separated from the external field in 1960-1970,1970-1980,1980-1990 and 1990-2000 were also calculated and analyzed.Results showed that X component of external field variation was increased firstly,then decreased with time.The chang... |
