摘要
This paper presents simulated results of the ionospheric behavior during few geomagnetic storms,which were occurred in the different seasons. The numerical model for ionosphere-plasmasphere coupling wasused to interpret the observed variation ofionosphere structure. Reasons why the positive storms are dominantin the winter whereas the negative ones are dominant in the summer season present the special interest forthe mid-latitude ionosphere. A theoretical analysis of the processes controlling the ionospheric response tothe geomagnetic storms has showed a good agreement between the simulated results and measurements, aswell as the crucial role of the neutral composition variations to fit the calculated and the observed ionosphericparameters.
