                         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.",
