What is Clear Air Turbulance?
The term used for turbulence occurring in the absence of clouds or cloud-like elements in the visible area. It is often observed in jet-stream areas, particularly in the upper troposphere to lower stratosphere. Open-air turbulence can also be seen near mountains and in closed low-pressure centers when there is wind shear.
