Abstract利用双频GPS接收机的观测数据研究了低纬度(海南,19.5°N,109.1°E)地区电离层电子柱含量(Total Electron Content,TEC)在2012年7月15-17日磁暴期间的扰动变化特征。在该磁暴期间的15、16日分别观测到了电离层正、负相暴,电离层垂直柱电子含量(Vertical Total Electron Content,VTEC)变化非常大,与宁静期间平均值相比,幅度可达35TECU;16日与15日相比,VTEC最大变化幅度为45TECU.这是目前观测到的电离层负相暴期间TEC变化幅度最大的现象。这次观测到的电离层正负相暴期间TEC扰动变化现象极可能分别是由渗透电场和扰动发电机电场所致。
Other AbstractWith the total electron content(TEC) data from GPS receiver located at ionospheric station Hainan (19.5°N, 109.1°E), disturbances of ionospheric TEC in geomagnetic storm from 15 July to 17 July 2012 are studied. During the storm time, both ionospheric positive and negative storms happened and the ionospheric vertical total electron content(VTEC) much disturbed. To compare it with the quite time, the largest variation of TEC is 35 TECU(total electron content unit). To compare it with that on July 15, the largest variation of TEC is 45 TECU, and it is the biggest variation of the TEC in the ionospheric negative storm up to date. By discussing, the TEC disturbed in the ionospheric positive and negative storm may be caused by the prompt penetration electric fields and disturbed dynamo electron fields, respectively. ©, Chinese Research Institute of Radiowave Propagation.
