             abstract = "The space weather events originated in the Sun can affect the 
                         whole thermosphere-ionosphere system at all latitudes. During such 
                         events disturbance electric fields (undershielding or 
                         overshielding) can penetrate from high to low latitudes causing 
                         significant disturbances in the electron density distribution and 
                         in the equatorial ionization anomaly (EIA) development. Besides 
                         that, the large amount of energy deposited in the polar region 
                         during disturbed periods will be responsible for the generation of 
                         disturbed winds that will flow towards the equator where they 
                         produce a disturbance dynamo which also affects the EIA density 
                         distribution. The TIDs and TADs are also sources of disturbances 
                         that propagate at high velocity reaching the equator 2-3 hours 
                         after the beginning of the magnetic storm. Particle precipitation 
                         is an additional source of perturbation at high latitudes as well 
                         as at the South Atlantic Magnetic Anomaly, where the conductivity 
                         can be affected by the extra ionization. Modeling the ionosphere 
                         during such disturbed periods is one of the most challenging tasks 
                         due to the complexity of the phenomena that affect the 
                         thermosphere environment as a whole. In this work we use the 
                         Sheffield University Plasmasphere-Ionosphere Model at INPE 
                         (SUPIM-INPE), to simulate the effects that were observed at the 
                         low latitude ionosphere in the South America longitude sector 
                         during some magnetic storm event. For some storms a few models are 
                         tested for the disturbed electric field and for the disturbed 
                         wind. A particle precipitation model is included in SUPIM, in 
                         order to test the ionospheric response to the enhanced 
                         conductivity.",
