Why does air turbulence occur during the flight? Turbulence, an unstable airflow, is often generated in the atmosphere due to uneven thermal distribution and terrain blocking, which is the main reason for aircraft turbulence.

Shen Haijun, professor and doctoral advisor of the School of Aeronautics and Mechanics of Tongji University, said: "Most of the turbulence is mild and lasts for a short time; only a small part of the turbulence is strong, Singapore Airlines flight probably encountered extreme turbulence. This turbulence is like an invisible hand, which makes the aircraft throw up and press down. "
