Abstract

The evolution of summer katabatic wind events over the steep slopes of Adélie Land is examined, with emphasis on the sudden cessation of these events. Different idealized large-scale forcings are considered, including a situation that comes very close to one observed during the IAGO (Interaction Atmosphère Glace Océan) campaign, held in the region in November–December 1985. The hydrostatic meso-γ-scale atmospheric model MAR (Modèle Atmosphérique Régional) is used to assess the sensitivity of the simulated cessation process to a prescribed large-scale forcing.
