چکیده
In this paper, we deal with the effect on the refractive index of seasonal anomaly in height of the ionospheric F2 peak for both, collisional and collisionless cases in the by using the real geometry of Earth’s magnetic field for north hemisphere. It is possible to say that there is an anti-symmetric harmony between the electron density and the all waves (for collisional and collisionless cases) at in hour when the seasonal anomaly occurs while there is an exact harmony in the real part of extra-ordinary

Variations of electron density based on long-term incoherent scatter radar and ionosonde measurements over Millstone Hill
[1] Measurements from the incoherent scatter radar (ISR) and ionosonde over Millstone Hill (42.6 N, 288.5 E) are analyzed to explore ionospheric temporal variations. The F2 layer peak density NmF2, peak height hmF2, and scale height H are derived from a Chapman a layer fitting to observed ISR electron density profiles. Diurnal, seasonal, and solar activity variations of the ionospheric characte...
متن کاملVariation of ionospheric slab thickness over South Africa
Ionospheric slab thickness is defined as the ratio of TEC to maximum electron density of the F-region (NmF2), proportional to the square of the F2-layer critical frequency (foF2). It is an important parameter in that it is linearly correlated with scale height of the ionosphere, which is related to electron density profile. It also reflects variation of the neutral temperature. Therefore, ionos...
متن کاملInvestigating the effect of the removing well-known periods from TEC time series data in identifying seismo-ionospheric anomaly
Iran is situated on one of the two largest seismic belt of the world which is called Alpa. The occurrence of damaging earthquakes all around the country causes a lot of pecuniary losses and casualties. The prediction of this phenomenon can have a profound impact on reducing the risks which are posed by it. Among the earthquake predictors, which are of interest to many scholars today, we can men...
متن کاملVariations of Scale Height at F-Region Peak Based on Ionosonde Measurements during Solar Maximum over the Crest of Equatorial Ionization Anomaly Region
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 gr...
متن کاملVariability of F2-layer peak characteristics at low latitude in Argentina for high and low solar activity and comparison with the IRI-2016 model
This work presents the study of the variability of foF2 and hmF2 at a low latitude station in South America (Tucumán, 26.9°S, 294.6°E; magnetic latitude 15.5°S, Argentina). Ground based ionosonde measurements obtained during different seasonal and solar activity conditions (a year of low solar activity, 2009 and one of high solar activity, 2016) are considered in order to compare the ionospheri...
