abstract = "In this work we use ionospheric data from two low-latitude
stations located north and south of the geomagnetic equator, at
approximately the same magnetic longitude, in order to study the
occurrence of the F-3 layer. The location of the stations being at
almost geomagnetically conjugate points is such that the effects
of the electric field/vertical plasma drift and diffusion will be
almost symmetric around the magnetic equator. Under this
configuration it is possible to deduce the effect of meridional
wind in the F-3 layer occurrence. Our results show that during the
December solstice the layer will be present at the Southern
Hemisphere (SH) location in 97% of the days and in the Northern
Hemisphere (NH) location in only 4% of the days. In the June
solstice the situation is reversed with the occurrence in the NH
being 82% and 16% in the SH. For the March equinox the occurrence
is low at both locations (4% in NH and 7% in SH), being mainly
present during magnetically disturbed periods. The analysis of the
effective meridional wind based on the Horizontal Wind Model and
on the asymmetry of the F layer peak height observed at the two
locations confirms the ubiquitous role of the wind in the F-3
layer formation and/or persistence during both quiet and disturbed
periods. The B0 parameter, that is a measure of the thickness of
the bottomside F region profile, revealed to be a good proxy for
the F-3 layer occurrence.",
