The atmospheric circulation over Antarctica during January 1994 is simulated using a limited area model, Eta model (version 1993, 55km horizontal resolution, 17 levels). The simulations are performed with initialized analyses from European Centre for Medium Range Weather Forecasts (ECMWF) as initial and boundary conditions. The results are in good agreement with the analyses even if the mesoscale features on the high Plateau are poorly represented. The model deficiency over the Plateau is emphasised in the medium-range simulation. Additional comparisons of model results and AWS observations will be presented.

Abstract
The atmospheric circulation over Antarctica during January 1994 is simulated using a limited area model, Eta model (version 1993, 55km horizontal resolution, 17 levels). The simulations are performed with initialized analyses from European Centre for Medium Range Weather Forecasts (ECMWF) as initial and boundary conditions. The results are in good agreement with the analyses even if the mesoscale features on the high Plateau are poorly represented. The model deficiency over the Plateau is emphasised in the medium-range simulation. Additional comparisons of model results and AWS observations will be presented.
