This paper presents results of the analysis of the ionospheric F2 layer peak height hmF2 variation under disturbed geomagnetic conditions over middle latitudes. The analysis was carried out using manually checked hourly hmF2 values derived from electron density profiles obtained at selected ionospheric stations of the Northern (NH) and Southern hemisphere (SH) within the last solar cycle. We studied seasonal, latitudinal and longitudinal dependence of the hmF2 variation for storm main and recovery phases. Our results indicate an importance of fully understanding the local patterns of hmF2 variations for the development of ionospheric models.
