                         show long- and shortterm variations in the MLT region is already 
                         well-known. From theoretical and observational studies, the 
                         nonlinear interactions between tides, or tides and planetary 
                         waves, have been proposed to explain the tidal variability with 
                         the same periods as observed in the winds. In this work, hourly 
                         horizontal winds obtained by meteor radar at S{\~a}o Jo{\~a}o do 
                         Cariri (7.4°S, 36.5°W) during January and February 2005, have been 
                         used to investigate the variability of atmospheric tides in the 
                         presence of quasi-twoday wind enhancements. Spectral analysis for 
                         meridional winds shows the presence of additional peaks with 
                         periods near 16 hours, suggesting nonlinear coupling between the 
                         2-day wave and the diurnal tide in the equatorial MLT region. 
                         Cross-correlation and bispectral analysis supports the existence 
                         of the relationship between the quasitwo-day-wave and the diurnal 
                         tide.",
