The circum-Antarctic ice-shelves respond to a more positive Southern Annular Mode with regionally varied melting [PDF]
Communications Earth & Environment, 2022 Positive phases of the Southern Annular Mode lead to enhanced basal melt overall in the Antarctic ice shelves, with strong losses in the Bellingshausen and Western Pacific sectors and gains in the Amundsen Sea, according to ice-ocean model experiments.

Onset and Evolution of Southern Annular Mode-Like Changes at Centennial Timescale [PDF]
Scientific Reports, 2018 The Southern Westerly Winds (SWW) are the surface expression of geostrophic winds that encircle the southern mid-latitudes. In conjunction with the Southern Ocean, they establish a coupled system that not only controls climate in the southern third of ...

Relationship between the southern annular mode and southern hemisphere atmospheric systems Relação entre o modo anular sul e os sistemas atmosféricos no hemisfério sul [PDF]
Revista Brasileira de Meteorologia, 2009 Seasonal relationship between the Southern Annular Mode (SAM) and the spatial distribution of the cyclone systems over Southern Hemisphere is investigated for the period 1980 to 1999.

Plastic Behaviour Buffers Climate Variability in the Wandering Albatross [PDF]
Ecology and EvolutionClimate change has marked effects on global weather patterns and oceanic systems, impacting animal behaviour and fitness in potentially profound ways. Despite this, we lack detailed information about species' responses to climatic variation.

Quantifying Southern Annular Mode paleo-reconstruction skill in a model framework [PDF]
Climate of the Past, 2021 Past attempts to reconstruct the Southern Annular Mode (SAM) using paleo-archives have resulted in records which can differ significantly from one another prior to the window over which the proxies are calibrated. This study attempts to quantify not only

Unusual Southern Hemisphere tree growth patterns induced by changes in the Southern Annular Mode [PDF]
, 2012 Recent changes in the summer climate of the Southern Hemisphere extra-tropics are primarily related to the dominance of the positive phase of the Southern Annular Mode. This shift in the behaviour of the Southern Annular Mode—essentially a measure of the

Antarctic sea ice regime shift associated with decreasing zonal symmetry in the Southern Annular Mode [PDF]
The Cryosphere, 2023 Across the long-term (∼43-year) satellite record, Antarctic sea ice extent shows a small overall circumpolar increase, resulting from opposing regional sea ice concentration anomalies.

Influence of the Tropics on the Southern Annular Mode [PDF]
Journal of Climate, 2012 Abstract Perturbations in the southern annular mode (SAM) are shown to be significantly correlated with SST anomalies in the central tropical Pacific during austral winter and SST anomalies in the eastern tropical Pacific during austral summer.

Assessing the impact of suppressing Southern Ocean SST variability in a coupled climate model
Scientific Reports, 2021 The Southern Ocean exerts a strong influence on global climate, regulating the storage and transport of heat, freshwater and carbon throughout the world’s oceans.
