turbulence

As long as we fly, we often feel the turbulence of the plane. In bad weather, violent bumps make the plane float like leaves in the wind. Some popular science experts also pointed out more vividly that when the plane bumps, it is like swimming or taking a boat, and suddenly it meets a wave, lifting or falling people or boats.

When the waves appear in a certain place is often unpredictable, and you never know when it will come. In fact, turbulence caused by airflow is as difficult to predict as waves, and in most cases it can only be judged by the experience of pilots. Flight attendants generally do not provide service 20 minutes after the plane takes off and 30 minutes before the plane lands.

The reason is that these two time periods are in the climbing stage and the descending stage respectively, and when the aircraft passes through the changing high-altitude airflow in the troposphere, it is easy to cause instability and turbulence of the aircraft.
