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.",
