Short summary
The Hintereisferner Experiment (HEFEX) investigated spatial and temporal dynamics of the near-surface boundary layer and associated heat exchange processes close to the glacier surface during the melting season. Turbulence data suggest that strong changes in the local thermodynamic characteristics occur when westerly flows disturbed prevailing katabatic flow, forming across-glacier flows and facilitating warm-air advection from the surrounding ice-free areas, which potentially promote ice melt.
