Climatology of the three coastal Antarctic stations Dumont d'Urville, Neumayer, and Halley
Long term air and snowfall chemistry measurements have been performed at the three coastal Antarctic stations Dumont d'Urville (66°40′S, 140°1′E), Neumayer (70°39′S, 8°15′W), and Halley (75°35′S, 26°19′W). The results have to be interpreted and compared with respect to the regional meteorologic...

Long term air and snowfall chemistry measurements have been performed at the three coastal Antarctic stations Dumont d'Urville (66°40′S, 140°1′E), Neumayer (70°39′S, 8°15′W), and Halley (75°35′S, 26°19′W). The results have to be interpreted and compared with respect to the regional meteorological conditions. In this study the 3-hourly synoptic surface observations taken at the three stations between 1991 and 1995, as well as the daily upper air soundings from 1993, are analyzed to describe the aspects of station climatologies relevant for the air and snowfall chemistry measurements discussed in the papers of this special section. Although the three stations are comparable, being situated close to the coastline of Antarctica, the meteorological conditions differ. While at Dumont d'Urville katabatic winds cause predominant strong and relatively dry surface winds from the interior of Antarctica, Neumayer and Halley are frequently influenced by easterly winds associated mostly with eastward moving cyclones. From April through October the wind field above 5 km is governed by a circumpolar vortex with westerly winds increasing in intensity with height.
