Abstract利用东亚和澳大利亚扇区不同地磁纬度台站和两个极区台站1974-1986年电离层垂直探测数据,分析了f0F2半年变化的主要特征.提出了产生f0F2半年变化的一种新的物理机制:低热层日潮的半年变化,引起赤道电急流幅度的半年变化,通过"喷泉效应"使得赤道电离层异常幅度产生半年变化,从而形成f0F2的半年变化.
Other AbstractIonospheric data observed at different geomagnetic latitudes in East Asia and Australia sector and two polar stations during 1974-1986 are used to analyze the characteristics of f0 F2 semiannual variation.A new mechanism of ionospheric f0 F2 semiannual variation is put forward in this paper.The semiannual variation of the diurnal tide in lower thermosphere induces the semiannual variation of the amplitude of equatorial electrojet.This causes the semiannual variation of the amplitude of equatorial ionospheric anomaly through fountain effect.This process induces the semiannual variation of f0 F2.
