I have a dimple too

• by Mote

  Could these dimples be caused by vertical von Karman vortices? http://en.wikipedia.org/wiki/Kármán_vortex_street

  Perhaps a steady slow flow of wind on top of a thin layer of sublimated gas covering the surface creating small dimple sized vertical swirls ( waves rolling along versus tornadoes) allowing areas of lower pressure on the surface promoting sublimation?
  the linear organization or patterning could then be horizontal interference. http://physics.stackexchange.com/questions/104778/how-can-a-wave-interfere-with-itself

  Hi Mote. You have this in Citizen Science, where I've added a comment. Maybe you should delete this discussion? 😉
