                         Jo{\~a}o do Cariri (7.4°S, 36.5°W) and Cachoeira Paulista 
                         (22.7°S, 45.0°W) presented typical variations consistent with 
                         nonlinear coupling between atmospheric wave modes. The spectral 
                         analysis of the hourly winds for both sites shows distinct power 
                         spectrum with peaks associated with diurnal and semidiurnal tides, 
                         quasi-two-day waves and 16-hour oscillations, mainly in the 
                         meridional wind component. The quasi simultaneous presence of 
                         these waves suggested that the 16-hour waves could have been 
                         generated from nonlinear interactions between the diurnal tide and 
                         2-day waves. Additionally, these relationships have been 
                         investigated using bispectral analysis and the results reinforce 
                         our interpretation.",
