Orographic cloud over glacial landform in Svalbard
by Rita Nogherotto, International Centre for Theoretical Physics (ICTP ), Trieste, Italy
The Hiorthfjellet mountain as seen from Longyearbyen. As the glaciers expand, due to their accumulating weight of snow and ice, they crush and scour surface rocks and bedrock, modeling the surface and forming the glacial landform. In the picture, the modeled mountain is overshadowed by an orographic cloud which develops in response to the forced lifting of air by the topography. Air passing over the mountain oscillates up and down forming a wave. Air cools through expansion as it rises, leading to condensation when reaching its saturation temperature and warms as it descends.
