Wondering what drives the non-linearity between temperature and surface melt on Antarctic ice shelves? Come find me at poster X4.23 in Hall X4 for a chat this afternoon!

Attached a photo of Nansen Ice Shelf to get your attention 👀❄️ #EGU25 #Antarctica #Cryosphere

To connect moisture sources to dominant weather patterns, we use Self-Organizing Maps (SOMs) alongside moisture tracking. This combination reveals how different atmospheric circulation patterns influence transport of moisture and snowfall across Victoria Land. 📊 (4/5)

We find a distinct split in moisture sources: northern Victoria Land receives moisture from the west, while southern Victoria Land gets moisture from the east, driven by cyclones in the Ross Sea. 💨❄️ (3/5)

We use a Lagrangian moisture diagnostic to map moisture sources of snowfall. The Southern Ocean is a key supplier of moisture, and in summer, when sea ice retreats, the Ross Sea becomes an important local source. This suggests future sea ice changes could impact snowfall in this region. 🌊➡️❄️ (2/5)

New paper out! ❄️ Coastal Victoria Land, Antarctica, is a region of extremes—from the polar desert of the McMurdo Dry Valleys, to areas with much more snowfall nearby. We studied where the moisture for this snowfall comes from—and the weather patterns that drive it! 🌍 💨 (1/5)
