North_Polar_Features-PIA13250.jpgLow Altitude North Polar Clouds (Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)60 visiteNorth Polar Troughs are the typical location to see evidence of strong Polar Surface Winds. This VIS image shows 'streamers' of clouds created by Catabatic Winds.
Catabatic Winds are created by cold air sinking at the Pole and then speeding along the surface towards the edge of the Polar Cap. When the Wind enters in the Troughs, the wind regime changes from "Laminar Flow" to "Choatic" and clouds of ice particles and/or dust become visible.
Orbit Number: 37.100; Latitude: 82,9725°; Longitude: 97,2613°; Instrument: VIS.

This image shows a small portion of the North Polar Sand Sea, an immense Region of sand dunes. The dunes are just starting to shed their Winter frost and will darken as Spring becomes Summer and the dark sand is revealed".MareKromium
