What does the term "bumpy air" typically describe in a flight?

The term "bumpy air" typically refers to turbulence experienced during the flight. Turbulence is caused by variations in air movement, which can occur due to a number of factors, including atmospheric pressure, jet streams, weather fronts, and obstacles such as mountains. When a plane flies through these irregular air currents, it can create a bumpy sensation for passengers and crew, resembling a jolting or shaking effect. Flight attendants are trained to manage passenger concerns during such occurrences and to ensure safety and comfort while the plane navigates through turbulent conditions.

Other terms mentioned, such as cloud formations at high altitude, wing flutter, and ground vibrations during landing, do not accurately capture the essence of "bumpy air," making turbulence the most appropriate definition in this context.
