Understanding Clear-Air Turbulence: What Travelers Need to Know
Clear-air turbulence (CAT) is a type of turbulence that occurs in cloudless skies, typically at high altitudes between 23,000 and 39,000 feet. Unlike turbulence associated with thunderstorms or mountain ranges, CAT is invisible to the naked eye and cannot be detected by conventional weather radar. This makes it particularly challenging for pilots to anticipate and avoid. (nationalgeographic.com)
What Causes Clear-Air Turbulence?
CAT is primarily caused by the interaction of air masses moving at different speeds and directions. The most common scenarios include:
-
Jet Streams: Fast-moving, narrow bands of wind high in the atmosphere that blow from west to east. The differing temperatures cause friction, leading to disturbances. (cbsnews.com)
-
Wind Shear: A sudden change in wind speed or direction over a short distance, creating invisible eddies and vortices that aircraft may encounter unexpectedly. (wxguys.ssec.wisc.edu)
How Does Clear-Air Turbulence Affect Flights?
While CAT is generally not dangerous, it can be unsettling for passengers. In rare cases, severe turbulence can lead to injuries, especially if passengers are not seated with their seatbelts fastened. According to the Federal Aviation Administration (FAA), between 2009 and 2023, 40 passengers and 166 crew members were reported seriously injured by turbulence. (nationalgeographic.com)

Stay Informed: Before your flight, check for any turbulence advisories or reports.
-
Buckle Up: Always keep your seatbelt fastened when seated, even if the seatbelt sign is off.
-
Follow Crew Instructions: Pay attention to announcements from the flight crew regarding turbulence.
