【摘要】：分析了2015年第173~175d太陽活動(dòng)對電離層以及地磁場的影響以及磁暴期間電離層延遲高階項(xiàng)對觀測值、靜態(tài)PPP的影響。結(jié)果表明,受173d爆發(fā)的日冕物質(zhì)拋射和冕洞高速流的共同影響,174d地磁持續(xù)擾動(dòng),達(dá)到大磁暴水平;L1、L2的二階項(xiàng)延遲最大值分別達(dá)到20 mm、40 mm,三階項(xiàng)延遲為2 mm、5mm;電離層高階項(xiàng)延遲對PPP的N方向的影響最為顯著,最大值達(dá)到了7.1mm,且呈向南偏移的趨勢,對U、E方向影響的最大值可達(dá)4.6mm,但沒有一致偏移的規(guī)律。
[Abstract]:The effects of solar activity on the ionosphere and geomagnetic field at 173d 175d, 2015, and the effects of the higher-order term of ionospheric delay on the observed values and static PPP during magnetic storms are analyzed. The results show that the continuous geomagnetic disturbance of 174d is affected by the coronal mass ejection and the high velocity flow in the coronal hole. The maximum of the second term delay and the third order term delay are 20 mm / 40 mm and 2 mm / 5 mm respectively, and the ionospheric high order term delay has the most significant effect on the N direction of PPP, the maximum value is 7.1 mm, and the trend is southward. The maximum value of the influence on the direction of UGU E can reach 4.6 mm, but there is no uniform deviation rule.
