Reanalysis representation of low-level winds in the Antarctic near-coastal region

Publication Type: Academic Journal

Source(s): Weather and Climate Dynamics, Vol 3, Pp 1415-1437 (2022)

Abstract: Low-level easterly winds encircling Antarctica help drive coastal currents which modify transport of circumpolar deep water to ice shelves, and the formation and distribution of sea ice. Reanalysis datasets are especially important at high southern lat...
