【摘要】：2012年為太陽活動(dòng)高峰年份,為了研究太陽活動(dòng)高年區(qū)域電離層的變化特征,該文選取了山東區(qū)域內(nèi)的SDCORS站點(diǎn),構(gòu)建了山東區(qū)域垂直電子含量(VTEC)球諧格網(wǎng)模型,對該年山東區(qū)域電離層時(shí)空變化規(guī)律進(jìn)行分析。實(shí)驗(yàn)研究表明,在空間變化上山東區(qū)域電離層表現(xiàn)出較強(qiáng)的緯度相關(guān)性,出現(xiàn)了明顯的分層現(xiàn)象。同時(shí)給出了山東電離層在時(shí)間上呈現(xiàn)出的時(shí)段變化、日變化、月變化、季節(jié)變化,發(fā)現(xiàn)VTEC受太陽活動(dòng)影響較大,除了存在明顯的單峰和雙峰結(jié)構(gòu)外,該年還發(fā)生了半年度異常現(xiàn)象。
[Abstract]:In order to study the characteristics of ionospheric variation in the solar active region in 2012, the SDCORS site in Shandong region was selected and the spherical harmonic grid model of vertical electron content in Shandong region was constructed. The temporal and spatial variation of the ionosphere in Shandong Province was analyzed in this year. The experimental results show that there is a strong latitude correlation and obvious stratification in the regional ionosphere of Shandong province. At the same time, the temporal, diurnal, monthly and seasonal variations of the ionosphere in Shandong Province are given. It is found that VTEC is greatly affected by solar activity, except for the obvious single-peak and bimodal structures. A half-year anomaly also occurred in that year.
