The spatial evolution of Antarctic katabatic winds in the area of Terra Nova Bay is examined using the three-dimensional version of the Université Catholique de Louvain-Modèle Atmosphérique Régional (UCL-MAR) mesoscale primitive equation models. The ability of the model to replicate classical linear mountain wave simulations is verified. Then, three-dimensional experiments are performed for the terrain configuration of Terra Nova (Ross Sea coastal zone) using different horizontal resolutions (5, 10, and 20 km). The model converges for resolutions lower than 10 km. Results are in qualitative agreement with available observations and previous modeling work. Strong katabatic winds are simulated with a jet over Terra Nova Bay. The model seems able to initiate the mesocyclonic activity in the Ross Sea due to the katabatic circulation.
