             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 whole thermosphere environment. 
                         It is well known that both, prompt penetration electric fields and 
                         large amounts of energy deposited in the polar region during 
                         disturbed periods, produce significant disturbances in the global 
                         electron density distribution, in particular, in the equatorial 
                         ionization anomaly development. Besides, the disturbance dynamo, 
                         traveling atmospheric disturbances, and traveling ionospheric 
                         disturbances also affect the equatorial ionization anomaly density 
                         distribution. In this work we use the Sheffield University 
                         Plasmasphere-Ionosphere Model at Instituto Nacional de Pesquisas 
                         Espaciais, to simulate the drastic effects that were observed at 
                         the low-latitude ionosphere in the Brazilian region during a very 
                         intense magnetic storm event, the so-called 2003 Halloween storms. 
                         In the absence of measured vertical drift during the storm, a new 
                         vertical drift deduced from the interplanetary electric field 
                         combined with the time variation of the F region virtual height is 
                         used as input. The simulation results showed that, in the case of 
                         the disturbed thermospheric wind, the ionospheric observations are 
                         better explained when a novel traveling wave-like disturbance 
                         propagating from north to south, at a velocity equal to 300 m/s, 
                         is considered.",
