Tidal amplitudes and phases deduced from Austral winter observations of OH Meinel (3,1) rotational temperatures at South Pole, Antarctica over the period 1994–2007 are presented here. Dominant periodicities in temperature data are seen at 24, 12, and 8 h. The amplitude of these wave oscillations shows significant variability during the months analyzed herein (April through September). In contrast to 12‐ and 8‐h waves, the 24‐h wave is stronger, more persistent, and coherent at South Pole. The observed amplitude variability in 24‐, 12‐, and 8‐h waves during the majority of the years analyzed is shown to be correlated. Phase variations of 24‐ and 8‐h waves with longitudes indicate that these waves are standing zonal wave number 0 waves.
