Links between hail hazard and climate modes of variability across Australia

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Climate modes of variability influence hail‐prone atmospheric conditions, but links between these drivers and hail hazard across Australia have not been well constrained. We examine relationships between the El Niño Southern Oscillation (ENSO), Indian Ocean Dipole (IOD), and Southern Annular Mode (SAM) and proxy‐derived hail‐prone days across the ...

Recent observations of Antarctic sea‐ice [PDF]

Weather, 1999
Antarctic sea-ice is potentially one of the most sensitive global warming indicators. Some re- cent studies using coupled ocean-atmosphere general circulation models suggest that C0,- induced warming and concomitant sea-ice re- duction might be less marked than in the Arctic (Gordon and O’Farrell 1997); certainly the ...

The Influence of Snow on Antarctic Sea Ice

, 2023
Snow cover affects the variability of the physical properties of sea ice. The snow’s unique thermal and optical properties govern the mass and energy fluxes in the sea ice system. They are important for sea ice evolution, energy exchanges between the ocean and the atmosphere, and light availability for ecosystems below the sea ice.

Sensitivity of near‐surface marine winds and wind stress in coastal Antarctica to regional atmospheric model configuration

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Marine winds near coastal Antarctica are important for sea‐ice variability and ocean circulation. We test the sensitivity of simulated winds to varying uncertain aspects of the atmospheric model configuration. Winds (each configuration a coloured solid line in the figure) are sensitive to model physics, and notably we find that wind stress over a ...

Last Interglacial subsurface warming on the Antarctic shelf triggered by reduced deep-ocean convection

Communications Earth & Environment
The Antarctic ice-sheet could have contributed 3 to 5 m sea-level equivalent to the Last Interglacial sea-level highstand. Such an Antarctic ice-mass loss compared to pre-industrial requires a subsurface warming on the Antarctic shelf of ~ 3 °C according

Contrasting impacts of two mesoscale cyclones on the South Shetland Islands' glaciers, northern Antarctic Peninsula

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study analyzed the impact of two mesoscale cyclones on the meteorology and glaciology of South Shetland Islands (SSI) glaciers, using in‐situ observations, ERA5 reanalysis data, and high‐resolution weather and glacier mass balance models. Mesoscale cyclones drive temperature drops, heavy snowfall, and strong winds over the SSI, significantly ...

Changes in the Antarctic’s Summer Surface Albedo, Observed by Satellite since 1982 and Associated with Sea Ice Anomalies

Remote Sensing, 2023
In polar regions, positive feedback of snow and ice albedo can intensify global warming. While recent significant decreases in Arctic surface ice albedo have drawn considerable attention, Antarctic surface albedo variability remains underexplored.

The Ice of the Southern Ocean [PDF]

, 1967
Regular sea ice observations off the coasts of Antarctica in the Mirny Station area have been made by the Soviet Antarctic Expedition since 1956. For eight years air ice reconnaissance over the Davis Sea has been made from Mirny Station during all the ...
