The statement about clear air turbulence often occurring in the vicinity of the jet stream is accurate because the jet stream is characterized by strong winds at high altitudes, which can create significant shear. This shear occurs when there is a difference in wind speed or direction between adjacent layers of air. As planes traverse areas near the jet stream, they can experience turbulence resulting from these abrupt changes, even when visibility is good and there are no clouds, hence, the term "clear air turbulence."

This phenomenon can be especially pronounced at the boundaries of the jet stream, where air masses of different temperatures and speeds interact. Pilots and air traffic controllers are trained to be aware of these conditions to better anticipate and manage in-flight turbulence, thereby ensuring the safety and comfort of passengers.
