                         Furthermore, changes in the electrical current system and in the 
                         circulation of winds in the upper atmosphere are produced. These 
                         changes disturb the ionosphere, for example, intensifying or 
                         inhibiting the Equatorial Ionization Anomaly, introducing 
                         anomalous variations in the amplitude and height of the F-layer 
                         peak, in the E-layer and in the occurrence of sporadic layers, 
                         among others effects. The disturbed electric fields will generate 
                         disturbed E x B drifts, which are very important for the 
                         electrodynamical processes at the equatorial regions. Furthermore, 
                         as one of the transport mechanisms for the charged particles is 
                         neutral wind drag, the plasma transport will also be modified by 
                         the disturbed wind. During magnetically disturbed periods, 
                         disturbances in several ionospheric parameters measured by 
                         Digisonde are observed, but the existing ionospheric models are 
                         unable to represent the observations properly. In this work we 
                         will use the ionospheric model SUPIM (Sheffield University 
                         Plasmasphere Ionosphere Model) in order to simulate the 
                         ionospheric behavior at different stations in the equatorial and 
                         low latitude regions in Brazil during some geomagnetically 
                         disturbed events. To find a pattern in these circumstances, we 
                         will adjust the input parameters, in this case, electric field and 
                         neutral winds, because we know that these parameters vary in these 
                         periods, until the results of the model can explain the electron 
                         density variations observed on Digisonde data at various 
                         stations.",
