Short Version


Dry, cold katabatics winds, as Piteraqs, cannot be seen as such in satellite images, but they occur together with certain low pressures: together with a polar low, a large comma and an occluded cyclone. In the image below an old occlusion is situated south of Greenland's southeastern coast within a very dry and cold air originated from the lowest layer of stratosphere, which is seen as a red area in the Meteosat Airmass combination.

In very high resolution images Piteraqs can be observed indirectly from blowing snow and foam.
