Clouds: Wave Clouds

Notes: Wave clouds are essentially the same as the M4 clouds. These are altocumulus clouds that, for the most part, remain stationary as the wind blows though the cloud. Wave cloud result from atmospheric standing waves.
These waves are created as stable air flows over a mountain range. As an air moves through the wave, it rises and descends repeatedly. If there is enough moisture in the atmosphere, clouds will form at the crests of these waves. In the descending part of the wave this cloud will evaporate.
