| Summary: | The Lambert Glacier drainage basin is a large area of the Antarctic which has been devoid of conventional meteorological observations, apart from the coastal meteorological stations. A mesoscale atmospheric model is adapted for use over the Antarctic continent, and is used with the coastal meteorological records to simulate boundary layer climatologies over the region. The results are well validated by new data from oversnow traverses and automatic stations around the basin. The CSU-Pielke (Pielke and Martin (1981)) numerical mesoscale model was tested for its suitability over Antarctica. Problems with the surface energy balance iteration scheme, sea ice surface temperatures, boundary layer height parameterisation and the representation of cloud in the radiation scheme over the Antarctic plateau needed to be overcome. Following sensitivity tests to surface parameters, mean summer and winter modelling results were verified using interpolated fields from observations available around the Lambert Basin. ... |
