Compound intense warming and precipitation events in the Patagonian Icefields and the Antarctic Peninsula Ice Sheet – Part 1: Event frequency, atmospheric circulation and impacts on glacier surface

Compound atmospheric phenomena driving Antarctic mean and extreme precipitation

Antarctic precipitation is the dominant positive term in the ice sheet surface mass balance, directly influencing its contribution to global sea level rise. In some coastal and ice-shelf regions, episodic extreme precipitation events can account for more than half of the annual snowfall total; yet while individual atmo...

Southern Hemisphere sea ice response to different flow regimes over the Antarctic Peninsula

Low-level winds over Antarctica are overwhelmingly controlled by the local orography. They, in turn, exert a large control over sea ice formation and transport. In this work, we investigate the relationship between Antarctic sea ice and the parameterized orographic gravity wave drag in the UK CMIP6 (Coupled Model Inter...

Possible Mechanisms Linking North American Cold Waves to Arctic Sea Ice and Eurasian Snow Cover Interannual Variations

Stratospheric polar vortex (SPV) stretching events are typically of 1–2 weeks in duration when the SPV is elongated and locally extends anomalously south into lower latitudes. Such events are often associated with extreme cold over the Great Plains to southern and eastern states of the US. Here, we present an observati...

The Ross Ice Shelf airstream: How Ross Sea cyclone activity leads to winter-time sea ice breakout events in McMurdo Sound in the years 2013–2024

Atmospheric River‐Cyclone Events Disrupting an Antarctic Peninsula Field Campaign: Dynamics, Mesoscale Wind Amplification, and Long‐Term Context

Extreme weather in the Antarctic Peninsula arises from interactions among large‐scale circulation variability, atmospheric rivers (ARs), extratropical cyclones, and complex coastal terrain, yet the linkages across these scales remain insufficiently resolved. We examine an austral‐summer storm sequence in early January...

Impact of oceanic and atmospheric variability on the annual ice dynamics of the Shirase Glacier (2014–2024), East Antarctica
