Abstract

The calendar year 2009 was relatively calm, climatologically speaking, for much of Antarctica, especially compared to the past two years which included ice shelf collapses juxtaposed with record-high sea ice extent. However, the total ice sheet melt during austral summer 2008/09 was the lowest of the 30-yr satellite record with no melt detected on the Ronne-Filchner and Ross Ice shelves, among other regions. In 2009, the polar atmosphere temperatures were persistently above average in the midto- lower troposphere during the winter. The latter half of the year was marked with short-lived anomalies lasting about one month. Nonetheless, the tropical El Niņo event in late 2009 did influence Antarctica, particularly through ridging in the South Pacific. In turn, this created anomalous meridional temperature advection patterns that subsequently led to regional sea ice extent and concentration anomalies and decreased precipitation to the west of the Antarctic Peninsula.
