满州里上空电离层之平均特性及暴时特性

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N_T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N_T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N_T和f₀F₂相对于月中值偏移量的均方根值δN_T和δf₀F₂都与磁Ap指数均方根值δAp之间存在一元线性相关. 

THE AVERAGE AND STORM-TIME BEHAVIORS OF IONOSPHERE OVER MANZHOULI

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 N_T 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 N_T.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 δN_T and δf₀F₂ from the month medians for TEC and f₀F₂ during magnetic storm.
