Turbulence in cloud-free conditions, typically found near the jet stream and at boundaries of air masses at high altitude. CAT cannot be detected by radar and is a significant hazard to enroute aircraft.
Why Clear Air Turbulence Matters for Pilots

More importantly, understanding Clear Air Turbulence helps pilots make sound go/no-go decisions and avoid hazardous conditions in flight. Weather-related accidents remain a leading cause of general aviation incidents.
