Abstract

Dumont d'Urville on the Antarctic coast is an area well known for the presence of strong katabatic winds. Since the austral summer 1979/80 a US-French joint experiment has been investigating the katabatic wind in this region. In early 1980 three automatic weather stations (AWS) were installed along a trajectory from Dome Charlie to Dumont d'Urville. Measurements from these stations include air pressure, temperature, wind speed and direction at ground level only. To supplement these data with information regarding the vertical structure and the advective changes in the katabatic flow, two airborne missions were undertaken in November 1980 along a route from Dome Charlie (Dome C) to Dumont d'Urville.
