             abstract = "Modeling the ionosphere during disturbed periods is one of the 
                         most challenging tasks due to the complexity of the phenomena that 
                         affect the electric fields and the thermosphere environment as a 
                         whole. It is well known that depending on the direction of the 
                         interplanetary magnetic field 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. In 
                         this work we use the Sheffield University PlasmasphereIonosphere 
                         Model at INPE (SUPIM-INPE), to simulate the drastic effects that 
                         were observed at the low latitude ionosphere in the Brazilian 
                         region during a very intense magnetic storm event. A few models 
                         are tested for the disturbed electric field and for the disturbed 
                         wind. The simulation results showed that the observations are 
                         better explained when considering a traveling waveform disturbance 
                         propagating from north to south at a velocity of the order of 200
