                         Cariri (7.4 °S, 36.5°W), from January to December 2005 were used 
                         to study quasi-orthogonal gravity waves in the meinel OH and OI 
                         5557 emissions. These gravity waves occurred simultaneously, 
                         propagating with phase fronts almost perpendicular each other. In 
                         this period, 135 nights were investigated and 9 such events were 
                         observed for the year 2005 in the OH emission spectra. However, 
                         only 2 events were analyzed in detail due to unavailability of 
                         coincident data from the meteor radar wind as well as the 
                         TIMED/SABER data for the majority of events. The goal of the 
                         research was to estimate the horizontal wind by calculating the 
                         parameters of these gravity waves (horizontal and vertical 
                         wavelength, propagation direction and observed period) and using 
                         Taylor-Goldenstein dispersion relation for gravity waves in order 
                         to compute the intrinsic frequency of the waves. This was achieved 
                         by computing the vertical wavelength of the waves using the phase 
                         difference between emission layers. The estimated horizontal 
                         background wind showed agreement with the data from the meteor 
                         radar wind with actual readings from the meteor radar. Horizontal 
                         background winds also filter gravity waves by permitting 
                         propagation only in certain directions. Temperature readings will 
                         also allow the investigation of atmospheric heating particularly 
                         in the ionosphere as the gravity waves dissipate energy.",
