New paper shows through a modelling experiment that reduced Antarctic sea ice may cause a positive feedback loop where the atmospheric response drive even further sea ice loss agupubs.onlinelibrary.wiley.com/doi/10.1029/...
Modeling the Impacts of Antarctic Sea Ice Decline: Responses of Atmospheric Dynamics
Increased zonal wind stress over the ocean surface leads to a decline in sea ice and a rise in sea surface temperature
Surface atmospheric changes become more evident during austral winter and sp...

Great new paper recently published providing a detailed analysis on how Antarctic atmospheric river behavior will change in the future
In today’s climate, #atmosphericrivers play a major role in bringing snowfall to #Antarctica. Have you ever wondered how that might change in the future?
Out today, our new study on the future frequency and precipitation impacts of Antarctic atmospheric rivers:

Rising atmospheric moisture escalates the future impact of atmospheric rivers in the Antarctic climate system - Communications Earth & Environment
Antarctic atmospheric rivers are projected to double in frequency and cause 2.5 times more precipitation by 2066–2100 due to rising atmospheric moisture, according to large ensemble climate simulation...

🧵 1/4 I'm very happy to share this comprehensive review paper covering atmospheric rivers in Antarctica. It was an idea that started during a workshop in Boulder back in summer 2023 and now is finally published thanks to an amazing team effort rdcu.be/d9nFY.

Fantastic paper out today that shows rainfall in Antarctica is an under-observed and under-appreciated risk to ice-sheet stability
📝NEW paper out today🥳
❄️We look at extreme snow and rain (yes, rain!) in West Antarctica over the Thwaites and Pine Island ice shelves.
In it, we show that atmospheric rivers - long, thin "rivers in the sky" that bring tons of heat & moisture - deliver huge amounts of snow... and even rain 🌧️

Exciting new research on Antarctic atmospheric rivers that, among many things, confirms that sea-ice acts as a buffer weakening atmospheric rivers before they make landfall. Disappearing sea ice will mean stronger atmospheric rivers in the future. #antarctica #meteorology
Vertical structure and surface impact of atmospheric rivers reaching antarctic sea ice and land
Recent extremes in Antarctic temperature, surface melt and sea ice loss have been robustly linked to the occurrence of atmospheric rivers (ARs). Howev…

New research shows that warm Southern Ocean sea surface temperatures are mainly to blame for record-low 2023 sea-ice extent. As long as sea surface temperatures remain elevated, sea ice extent will likely remain limited. www.nature.com/articles/s43...
