                         atmospheric sodium in the 80-110 km height range. The winds were 
                         measured by a meteor radar installed at Cachoeira Paulista (23 
                         degrees S, 45 degrees W), and the sodium density was measured by 
                         lidar at Sao Jose dos Campos (23 degrees S, 46 degrees W). The 
                         distance between the two sites is 102 km. During the southern 
                         winter of 1999 a total of 320 hours of simultaneous measurements 
                         were obtained. Within this measurement period a large number of 
                         sporadic sodium (Ns)layers were observed. As we have previously 
                         reported, on many occasions Ns layers occur near the peaks of 
                         descending structures in the sodium layer. The simultaneous 
                         measurements reported here enable us to show that the descending 
                         structures involved are closely related to similar structures in 
                         the meridional wind profile. A clear tidal structure is visible in 
                         the sodium layer, with a vertical wavelength which corresponds to 
                         that seen in the meteor winds.",
