The katabatic wind regime at Adelie Land, Antarctica
Abstract The coastal sections of Adelie Land in East Antarctica experience the strongest and most persistent slope (katabatic) winds recorded about the continental periphery. The area was first explored during Mawson's 1911–14 Australasian Antarctic Expedition; the annual average surface wind s...

Abstract The coastal sections of Adelie Land in East Antarctica experience the strongest and most persistent slope (katabatic) winds recorded about the continental periphery.
