Wind-Associated Melt Trends and Contrasts Between the Greenland and Antarctic Ice Sheets
peer reviewed Föhn and katabatic winds (downslope winds) can increase ice sheet surface melt, run-off, and ice-shelf vulnerability to hydrofracture and are poorly constrained on the Greenland and Antarctic ice sheets (GIS and AIS). We use regional climate model simulations of the GIS and AIS to quan...
