Can current reanalyses accurately portray changes in Southern Annular Mode structure prior to 1979?

Gareth J. Marshall et al.

Summary: The study demonstrates that ERA5 best reproduces Antarctic near-surface air temperatures in the early period and is also the most homogeneous reanalysis across the early and late periods, indicating a significant change in the relationship between Southern Annular Mode (SAM) and Antarctic near-surface air temperatures between the two periods.

On the drivers of temperature extremes on the Antarctic Peninsula during austral summer

Sai Wang et al.

Summary: This study investigates the role of atmospheric circulation on driving the temperature extremes over the Antarctic Peninsula during austral summer. It is found that intraseasonal oscillations contribute the most to the formation and development of temperature extremes, while synoptic variations affect the temperature anomalies around peak time. The upstream ISO Rossby wave packet propagating along the jet stream south of Australia precedes the extreme temperature events.

Central tropical Pacific convection drives extreme high temperatures and surface melt on the Larsen C Ice Shelf, Antarctic Peninsula

Kyle R. Clem et al.

Summary: Extreme summertime surface melt and record-high temperature events on the eastern Antarctic Peninsula and Larsen C Ice Shelf are triggered by deep convection in the central tropical Pacific, which transports warm and moist air to the area, causing strong foehn warming and surface melt. Variability in central tropical Pacific convection is a key driver of surface mass balance and extreme high temperatures in the area.

Intense atmospheric rivers can weaken ice shelf stability at the Antarctic Peninsula

Jonathan D. Wille et al.

Summary: This study uses an atmospheric river detection algorithm, regional climate model, and satellite observations to investigate the processes leading to the dramatic collapse of ice shelves in the Antarctic Peninsula. The research finds that intense atmospheric rivers have a 40% probability of inducing extremes in temperature, surface melt, sea-ice disintegration, or large swells that destabilize the ice shelves. This phenomenon was observed during the collapses of the Larsen A and B ice shelves. The study also reveals that 60% of calving events from 2000-2020 were triggered by atmospheric rivers, highlighting their significant role in ice shelf stability.

Extreme Temperatures in the Antarctic

John Turner et al.

Summary: This study presents the first Antarctic-wide analysis of extreme near-surface air temperatures, examining temperature distributions, extreme high and low temperatures, variability, and trends at 17 stations. Record high temperatures were mainly influenced by air masses passing over high terrain, while record low temperatures were associated with positive sea ice anomalies over certain seas.

Warming events projected to become more frequent and last longer across Antarctica

Sarah Feron et al.

Summary: Projections indicate that summertime warming events in Antarctica will become more frequent, longer-lasting, and significantly increase in number by the end of the century. This anticipated rise in warming events may lead to enhanced surface melt in coastal areas, posing a risk to the future stability of Antarctic ice shelves.

Antarctic skin temperature warming related to enhanced downward longwave radiation associated with increased atmospheric advection of moisture and temperature

Kazutoshi Sato et al.

Summary: The study found significant warming in the Antarctic region during spring, autumn, and winter over the past 70 years, primarily due to increases in downward longwave radiation. Additionally, negative sea level pressure trends and associated circulation also contributed to the warming in Antarctica.
