Resumen:
This paper will present results of the analysis of the ionospheric F layer peak parameters
variability under quiet and stormy conditions over middle latitudes. The analysis was carried out
using hourly foF2 and hmF2 values measured at the selected ionospheric stations of the Northern
and Southern hemisphere. The observations were compared with the IRI model outputs. Quality
of the STORM model storm-time corrections was also evaluated. In our analysis we used data
from some ionospheric stations (e.g., Pruhonice, El Arenosillo, Grahamstown, Athens), which
were not included in the development or the previous validation of the STORM model. Overall
summary of the evaluation results for Northern hemisphere indicates the decreasing ability of the
model to simulate storm effects with decreasing latitude. For Southern hemisphere an efficiency
of the model corrections seems to be considerably lower and decreases with increasing latitude.
An improvement of a recovery phase representation is significantly lower. As for seasonal
dependence of the quality of the storm-time corrections, the model gives better results for
summer storms.
