【摘要】:2012年为太阳活动高峰年份,为了研究太阳活动高年区域电离层的变化特征,该文选取了山东区域内的SDCORS站点,构建了山东区域垂直电子含量(VTEC)球谐格网模型,对该年山东区域电离层时空变化规律进行分析。实验研究表明,在空间变化上山东区域电离层表现出较强的纬度相关性,出现了明显的分层现象。同时给出了山东电离层在时间上呈现出的时段变化、日变化、月变化、季节变化,发现VTEC受太阳活动影响较大,除了存在明显的单峰和双峰结构外,该年还发生了半年度异常现象。
[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.
