摘要
假设在低纬地区有一根磁力线振荡,从基本方程出发,推算出地面各点的磁场扰动情况,模拟低纬Pc3脉动。对比低纬地区Pc3脉动的观测结果,可以看出用这种理论数值模拟的结果基本上与观测事实相符,用它可以初步解释低纬Pc3脉动的频率特性和偏振特点。
In this paper, it is assumed that a field line oscillates at low latitude. The magnetic disturbances on the ground are calculated and the low-latitude Pc3 pulsations are simulated from basic equations. Comparing with Pc3 pulsations observed at low latitudes, it can be seen that the simulated results are almost as same as real observations. So this theory can explain the characteristics of both frequency and polarization for low-latitude Pc3 pulsations.
