Abstract:

The study of foF2 diurnal variation at Dakar station during the solar maximum under the shock activity conditions of variable duration (One-day-Shock, Two-days-Shock and Three-days-Shock) confirms the seasonal dependence profiles. Thus, in spring and summer, we note the absence of electrojet which prove the Plateau and Dome profiles. In autumn, except Three-days-Shock where foF2 data graph gives afternoon peak profile, the noon bit out profile is recorded during this season. In winter, foF2 data show the noon bit out profile with a high morning peak trending towards that of the morning peak. The winter anomaly is observed during the different types of shock activity. Spring and autumn are marked by the signature of the reversal electric field.

Keywords: One-day-Shock, Two-days-Shock, Three-days-Shock, Solar Maximum, foF2.
