This week check, out this video from Ice Alive which shows unique cloud patterns over a glacier in Greenland. The cloud patterns are likely influenced by glacial ice, which cools the air above the surface of the glacier. A prime example of this is what is known as katabatic winds, which occur when cooling produces a cold, dense air mass above a glacier that then flows downhill.
Glaciers and ice sheets are big & cold enough to influence the atmosphere above them. One example is cold #katabatic winds flowing off-ice.
