abstract = "The interactions between the solar wind and the
magnetospherethermosphere-ionosphere system produce variations on
upper atmospheric dynamic to different spatial and temporal
scales. The episodic increases in energy during geomagnetic storms
results in additional variations in dynamics, chemistry as well as
in the composition of the atmosphere. In this paper we have used
winds from meteor radar at Cachoeira Paulista (22.7°S, 45°W) to
investigate a possible relationship between variations in the
dynamics of the upper mesosphere and lower themosphere (MLT)
region and geomagnetic storm events on July 2004. The wind
behavior presented a different pattern from those observed before
and after the period of the geomagnetic storms, mainly in the
meridional component. The possible relationship between diurnal
tide variations and the geomagnetic storm events are discussed.",
