Recent ground-based measurements of the neutral winds and temperatures at mesospheric heights near the Earth's rotational pole, at Amundsen-Scott Station, show that the neutral atmosphere has a restricted zonal wavenumber behavior at very-high latitudes. This can be interpreted as the natural response of the atmosphere to the boundary conditions at the rotational pole (s). Experimentally, mostly planetary-scale waves have been observed during the austral winter.
