Why did the plane keep ringing last night?

Because of the strong convective weather.

The plane will be a little bumpy, so there will be noise. When encountering airflow, the engine will make a loud noise. Make a lot of noise.

The airflow in the engine is very fast, and it will make a loud noise when it meets the slow airflow. Just like a gun, when the airflow in the barrel flows out of the barrel, it will collide with the airflow outside.
