Wave Clouds by Mornington Island, Australia

Australia – August 16th, 2012

The atmospheric internal waves that form wave clouds are created as stable air flows over a raised land feature. In this image, the raised land feature is Mornington Island, in the Gulf of Carpentaria, Australia. As an air mass travels through the wave, it undergoes repeated uplift and descent. If there is enough moisture in the atmosphere, clouds will form at the cooled crests of these waves. In the descending part of the wave, those clouds will evaporate due to adiabatic heating, leading to the characteristic clouded and clear bands.
