Abstract In this paper we present some preliminary findings from the preparation of a gravity wave climatology at Halley IV station, Antarctica, using data gathered during the second phase of the British Antarctic Survey’s Stable Antarctic Boundary Layer Experiment in 1991 (STABLE II). The method of “beamsteering” is used to evaluate wave parameters from data gathered using an array of six microbarographs. Results are presented from artificial data designed to test the beamsteering code and also to compare it with the “correlation” method used in a previous study. Two case studies which illustrate the kind of wave events observed during the STABLE II programme are described.
