Abstract
We have utilized a simplified second‐order turbulence closure scheme to predict acoustic scattering profiles as a function of time from a numerical model of the atmospheric boundary layer under statically stable conditions. Comparisons have been made with data obtained at South Pole Station, Antarctica. Two cases in particular were analyzed. The first was that of warm air advection over a cold surface. The second involved the thin boundary layer and elevated scattering layers that form when the geostrophic pressure gradient force opposes the thermally driven slope winds characteristic of the East Antarctic ice sheet.
