This Photo was top 12 in ‘The Weather Channel Photo Competition’ 2012 and will feature in the 2012 Weather Channel Calender .
I just loved how the clouds look like they were painted in the sky.
This photo was taken near Mount Kaputar National Park, Narrabri, NSW Australia. Early August when our weather is much warmer. It is late winter/early spring.
Where stable moist air flows over a mountain or a range of mountains, a series of large-scale standing waves may form on the downwind side. If the temperature at the crest of the wave drops to the dew point, moisture in the air may condense to form lenticular clouds. As the moist air moves back down into the trough of the wave, the cloud may evaporate back into vapor. Under certain conditions, long strings of lenticular clouds can form near the crest of each successive wave, creating a formation known as a ‘wave cloud.’ The wave systems cause large vertical air movements and so enough water vapor may condense to produce precipitation. The clouds have been mistaken for UFOs (or “visual cover” for UFOs) because these clouds have a characteristic lens appearance and smooth saucer-like shape. Bright colors (called Irisation) are sometimes seen along the edge of lenticular clouds.1 These clouds have also been known to form in cases where a mountain does not exist, but rather as the result of shear winds created by a front.
