Data analysis and application of the geomagnetic data at Langfang and Fuke geomagntic stations

Wang Jing;Cheng Yonghong;Shi Liqin;National Space Science Center, CAS;  
There is high relativity and the similar variation during geomagnetic storm and quiet periods between the data of Langfang, Fuke geomagnetic stations and Shisanling, Sanya, MMB geomagnetic stations. Based on the data of the two stations, the work of extracting the geomagnetic pulsations was carried out using the Fourier transform. The research results show that the duration, average strength, variation of Pc5 pulsation and the duration, average strength, variations of Pi1 pulsation and the duration of Pi2 pulsation had the significant change during geomagnetic storm periods which form the basis for the study of relationship between pulsation and the relativistic electron flux enhancement event.
