In meteorology, clear-air turbulence (CAT) is the turbulent movement of air masses in the absence of any visual clues such as clouds, and is caused when bodies of air moving at …

2024年5月22日 · Clear-air turbulence happens most often in or near the high-altitude rivers of air called jet streams. The culprit is wind shear, which is when two huge air masses close to each …

2024年5月22日 · Clear-air turbulence is a "typically very violent" phenomenon that occurs at high altitudes, typically between 23,000 to 39,000 feet above sea level, said Hassan Shahidi, …

2024年5月24日 · Clear air turbulence is when erratic air currents occur in cloudless air between altitudes of 20,000 and 49,000 feet. One of the main causes of clear air turbulence is disrupted …

2023年10月12日 · Clear air turbulence is an atmospheric phenomenon that typically occurs at high altitudes where clear skies and more serene conditions prevail. Unlike the turbulence …

Clear Air Turbulence (CAT) is defined by the International Civil Aviation Organisation (ICAO) as turbulence generated in clear air, in regions without clouds, which is invisible to the pilot.

Clear air turbulence is turbulence not associated with cumuliform clouds, including thunderstorms, occurring at or above 15,000 feet. Clear air turbulence is not restricted to cloud-free air (75% …

2024年5月22日 · Clear air turbulence (CAT) is invisible and dangerous, as pilots have little warning when navigating through it. CAT is difficult to avoid, but pilots are trained to adjust …

Clear-air turbulence (CAT), erratic air currents that occur in cloudless air between altitudes of 6,000 and 15,000 metres (20,000 and 49,000 feet) and constitute a hazard to aircraft.

2024年12月3日 · Clear Air Turbulence is a form of atmospheric disturbance caused by sudden and invisible changes in wind speed and direction. It usually happens at altitudes above …
