THE AVERAGE AND STORM-TIME BEHAVIORS OF IONOSPHERE OVER MANZHOULI
-
摘要: 本文对1983年满州里(磁纬38.07°)的测高仪资料和子午仪卫星资料进行了处理.前者主要是对F2层临界频率f0F2,而后者是对微分多普勒的总含量NT进行分析.得到满州里上空电离层之平均特性,以及磁暴期间电离层的一些异常变化.结果发现,满州里电离层的平均特性具有典型的季节异常,且f0F2和NT的变化呈现较好的一致性.满州里上空电离层的扰动大都发生在两分点季和冬季,且正相大多发生在冬季,双相大多发生在两分点季,负相大多发生在夏季和两分点季.得出1983年满州里暴时NT和f0F2相对于月中值偏移量的均方根值δNT和δf0F2都与磁Ap指数均方根值δAp之间存在一元线性相关.Abstract: This paper presents the reduction results of ionosonde data and NNSS measured data at Manzhouli (38.07 mag. lat.) during 1983. The average behaviors and some anomalies of storm-time variations of the ionosphere above Manzhouli are obtained by analysing the critical frequency f0F2 and TEC NT deduced from differential Doppler data.The results indicate that the behaviors of ionosphere in average show a typical seasonal anomaly and good agreement between the variations of f0F2 and NT.Most of the ionospheric disturbances over Manzhouli is occurred in Equinox and Winter. The positive disturbances mostly happened in Winter, mixing positive and negative ones in Equinox, and negative ones in Summer and Equinox.It is shown that the good linear correlation is existed between the RMS value δAp of magnetic index Ap and the RMS deriations δNT and δf0F2 from the month medians for TEC and f0F2 during magnetic storm.
