Wave Clouds
A wave cloud is a cloud form created by atmospheric standing waves. These waves are created as stable air flows over a mountain range, and can either form above or in the lee of the range. 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 crests of these waves. In the descending part of the wave this cloud will evaporate due to adiabatic heating, leading to the characteristic repeating cloud/clear bands. The cloud base on the leeward side is higher than on the windward side because precipitation on the windward side removes water from the air.
It is possible that convection from mountain summits can also result in the formation of wave clouds. This occurs as the convection forces the wave and lenticular wave cloud into the more stable air above.
