abstract = "Medium Scale Traveling Ionospheric Disturbances (MSTIDs) were
studied using detrended Total Electron Content (dTEC) maps and
keograms over South-Southeast of Brazil during the period from
December 2012 to February 2016. In total 826 MSTIDs were observed
and they present average values of horizontal wavelength, period,
and horizontal phase velocity of 445.19 ± 106.70 km, 23.58 ± 3.65
min e 322.68 ± 80.95 m/s, respectively. The direction of
propagation presented anisotropy depending on the season. In
addition, the occurrences of MSTIDs were during the daytime
between 11-15 LT in winter and other seasons near to solar
terminator (17-19 LT). Furthermore, the seasonality of MSTIDs has
a higher occurrence rate in winter. The MSTIDs characteristics
also suggest that gravity wave activities in the thermosphere,
mesosphere and troposphere could play an important role in
generating the MSTIDs.",
