abstract = "The thermospheric neutral wind plays important control in the
temporal and spatial ionospheric plasma distribution at equatorial
and low latitude sectors. For example, it is responsible for the
F3 layer formation and for the asymmetry in the equatorial
ionization anomaly crests. In this work, we have investigated the
effects of the neutral winds on both E and F region over the
Brazilian sector during one day, October 10, 2002, of Conjugate
Point Experimental (COPEX) campaign. To calculate the ionospheric
response to wind change the Sheffield University Plasmasphere
Ionosphere Model at INPE (SUPIM-INPE) was used, in which the winds
from two different versions of the Horizontal Wind Models (HWM93
and HWM07) were analyzed. As expected, the model results have not
shown wind effects in the control of the plasma distribution near
E region peak for equatorial and low latitude sectors. On the
other hand, the F region variations due to the winds are complex
and involve non-linear processes. Some changes in foF2 in response
to wind are seen after ~3 hours. There is evidence that, for the
day October 10, 2002, the lifetime of the equatorial ionization
anomaly crests after midnight was significantly increased due to
convergent winds near the conjugates points. The origin of such
winds may be from the equatorial midnight temperature maximum
(MTM) phenomenon. Equatorward wind contributes to increase the
poleward expansion of equatorial ionization crests.",
