The katabatic winds of Cape Denison and Port Martin
The Australasian Antarctic Expedition, 1912–14, led by Douglas Mawson, encountered incredibly strong, persistent katabatic winds at Cape Denison and along the coastal stretches of Terre Adélie and George V land (Fig 1). The mean wind speed at Cape Denison was 19.3 ms −1 [43.2 mph] which far surpasse...
