air turbulence的意思|示意

Air turbulence is an unpredictable change in the air flow that affects an aircraft, much like a wave or a rock in a river. It is a normal but unpleasant phenomenon, mainly caused by sudden changes in atmospheric pressure or the presence of objects such as mountains, thunderstorms, and even other aircraft in the sky.

When an aircraft passes through a patch of air turbulence, it can cause the plane to shake, dip, and sway. Turbulence is divided into two main types: clear air turbulence and thunderstorm turbulence. Clear air turbulence is a bumpy ride caused by invisible currents of air that can be set off by mountain peaks. Thunderstorm turbulence is usually caused by rapid changes in air pressure in or near thunderstorms.

The intensity of air turbulence varies from light to severe. Light turbulence is a slight bumpiness in the aircraft, but it can still cause items to shake around and it can cause discomfort. Moderate turbulence is more jarring, but still manageable. Severe turbulence can cause the aircraft to sway so strongly that uncontrolled objects, like food carts and unsecured passengers, are thrown around the cabin. In some cases, the aircraft’s wings could even be damaged, making it unsafe to fly in.

Being aware of air turbulence, and knowing what to do when it occurs can make air travel more comfortable and safer. Passengers should always wear a seatbelt while seated, and should try to remain seated and calm during turbulence. For pilots and airline crews, being aware of the potential risks and being prepared to take the necessary steps to minimize them is the best way to handle turbulent conditions.
