Abstract

Abstract

Longitude effect in the mid-latitude F region is studied in this paper, using monthly median value f₀F₂ and f₀F₁ observed at Changchun and Urumqi,China from 1956 to 1994. Results are compared with the IRI-90 model. Physical mechanism leading to the longitude effect is discussed with the help of the IRI-90 and MSISE90 models.
- Longitude effect of the ionosphere,
- UT effect of the ionosphere,
- Ionosphere-thermosphere coupling,
- Ionospheric modelling,
