A MULTISTATION OBSERVATION OF LOW-LATITUDE Pc3 GEOMAGNETIC PULSATIONS
-
摘要: 利用长春、北京、兰州三个低纬地区台站的地磁脉动观测资料,对低纬地区(1.21≤L≤1.43)Pc3脉动的频谱特性和偏振特性做了对比分析,并对低纬Pc3脉动的激发机制和传播过程进行了讨论。Abstract: In this paper the observational information of geomagnetic pulsations at 3 low-latitude stations,Changchun,Beijing,Lanzhou is used to analyse the characteristics of spectrum and polarization for Pc3 pulsations.Based on the nalysis the generation and propagation mechanism of low-latitude Pc3 pulsations are discussed.
