abstract = "Ground-based global navigation satellite systems (GNSS) receivers
have been used to monitor the meridional (north-south) development
of equatorial plasma bubbles (EPBs) at geomagnetically conjugate
points over the Brazilian sector. EPBs were studied using
detrended total electron content plots obtained from Boa Vista
(MLat: 9.6°N), Itacoatiara (MLat: 3.3°N), Col{\'{\i}}der (MLat:
5.0°S), and Cuiab{\'a} (MLat: 8.8°S) GNSS receivers. All GNSS
receivers are located approximately under the same magnetic
meridian. 655 nights with EPBs occurrence were analyzed using data
from January 2012 to February 2016. In 459 nights (\∼70%)
the EPBs presented a symmetric development with respect to the
geomagnetic equator. However, in 196 nights (\∼30%) the
EPBs presented an apparent asymmetry. The asymmetries are
characterized as a displacement of the EPBs to north (or south) of
the geomagnetic equator. The highest north (south) asymmetry
occurrence was observed during December to January (March to April
and September to October), and lowest during March to April and
August to September (December to January). To investigate these
asymmetries, we analyzed meridional wind data and used a numerical
model to simulate the EPBs evolution. Both meridional wind data
and numerical simulation results suggested that a trans-equatorial
meridional wind blowing to north (south) would be able to cause a
displacement of the EPBs to north (south) of the geomagnetic
equator.",
