Abstract EN
Scale height is an important parameter in characterizing the shape of the ionosphere and its physical processes.
In this study, we attempt to examine and discuss the variation of scale height, H m , around the F-layer peak height during high solar activity at the northern crest of the equatorial ionization anomaly (EIA) region.
H m exhibits day-to-day variation and seasonal variation, with a greater average daily variation during daytime in summer.
Furthermore, the diurnal variation of H m exhibits an abnormal peak at presunrise during all the seasons, particularly in winter.
This increase is also observed in the F2-layer peak height for the same duration with an upward movement associated with thermospheric wind toward the equator; this upward movement increases the N2/O ratio and H m , but it causes a decrease in the F2-layer maximum critical frequency during the presunrise period.
