Short summary
We study with numerical simulations whether changing glacier ice surfaces impacts the atmospheric boundary layer structure over a glacier. Under north-westerly flow, a gravity wave forms over the glacier valley. When the surrounding upstream glaciers are removed, the gravity wave is weakened and breaks earlier. This leads to stronger turbulent mixing over the remaining glacier and to higher temperatures. We suggest that glaciers influence each other and should be studied as a connected system.
