Scientific paper

Mesospheric Na data are used to characterize the gravity wave field in the mesopause region at the South Pole. The first lidar observations of Na layer dynamics show strong wave activity during the Antarctic winter. Data for June 25 and August 19, 1990, UT are presented. The total wave-induced variances in atmospheric density are 29 and 35 (percent) squared. The Na layer centroid height is very low during both observation periods. On June 25 a strong 12-h oscillation is observed in the bottomside of the Na layer which extends to altitudes as low as 74 km. The vertical displacement and temperature amplitudes associated with the 12-h oscillations are 1.9 km and 19 K, respectively. The characteristics of the 12-h wave are similar to the pseudotide observed at Svalbard by Walterscheid et al. (1986).
