This conceptual model describes katabatic winds on the southeastern coast of Greenland, where they are called Piteraqs. These may be in some cases even hurricane-force (up to speed of 80 m/s) winds that rush down from the high glacier down to the coast trough valleys. The same kind of winds occurs also on the coasts of Antarctica.

This module describes Piteraqsoccurring near Tasiilaq's synoptic station:

Near Tasiilaq the ocean is mostly open throughout the year, whereas in middle and northern Greenland and in Antarctica the sea ice reaches the coast for the greatest part of the year. This leads to a phenomenom called Polynia, which is described in the chapter Meteorological Physical Background.
