Clouds

  1. 1. Rarely Seen Cloud Formations<br />There seems to be no end to strange cloud formations! From Punch hole clouds to cloud vortices, enjoy these rarely seen cloud formations! <br />
  2. 2. Punch Hole Clouds may appear as a circular or oval holes in a layer of supercooled clouds; sometimes they assume a form of a perfect circle and persist for quite a long time, drifting together with the cloud layer. One explanation seems to blame the air traffic (the jet contrail intersections) combined with a thermal inversion (a circular motion of a rising warm air). Here is one, observed over the Gunnison Valley in Colorado:<br />
  3. 3. Another strange hole in the cloud, reported from Mobile, Alabama USA, Dec. 2003 (and covered by BBC <br />Photo taken in Melbourne, Australia in 2003<br />
  4. 4. It seems both rising and sinking air currents can create the same effect. Sometimes a very stable, uniform layer of high-altitude clouds can get "punched though" by a pocket of cold air, which sinks toward the ground - creating the circular hole formation<br />These "cloud holes" can look like the footprints of some celestial being (UFO enthusiasts rejoice!) or can be amazingly round, like this pair observed in Gallatin, Tennessee by Wayne Carter<br />
  5. 5. Cloud formations taken by NASA satellite<br />
  6. 6. More Incredible and Fascinating Clouds<br />
