                         Paulista (22.4 \◦S; 45.0 \◦W), Brazil, from June 
                         2013 to December 2015 using airglow images from OI 630.0 nm. 
                         During this period, 58 MSTIDs were classified as MSTIDs dark 
                         band(around 10 events), and periodic MSTIDs (48 events). Dark band 
                         MSTIDs present phase velocity between 50 and 200 m/s and 
                         propagation direction to Northwestward. On the other hand, 
                         periodic MSTIDs have a horizontal wavelength of 80 to 160 km, a 
                         period ranging between 5 and 45 minutes, the phase velocity of 50 
                         to 200 m/s, and propagation direction mainly to 
                         North-Northeastward. The parameters indicate that the periodic 
                         MSTIDs have different characteristics when compared with dark band 
                         MSTIDs, suggesting that the periodic MSTIDs are not generated 
                         through the well-known instability Perkins; in addition, this 
                         study indicates that the spectral characteristics found in Brazil 
                         are different from other regions such as Japan and Indonesia. 
                         Therefore, this article intends to investigate the generation 
                         mechanisms of the periodic MSTIDs. The anisotropy observed in the 
                         periodic MSTID propagation direction can be explained by the wind 
                         filtering mechanism.",
